Brad and Ashley were thrilled with the healthy baby girl, and were devoted to her. Ashley had refused to name Abby's father initially, but finally claimed it was her old friend Christian. Brad adopted Abby as a baby, and Abby grew to be a precocious child. After young Abby overhead that Victor Newman was her biological father, she was the one to tell him. Abby soon formed a strong bond with Victor, although it didn't lessen her love for Brad. Although Brad initially won custody of Abby during their divorce, he returned her to Ashley, who took Abby with her when she left to work in Hong Kong.
Abby later returned to the United States with her mother, and although she continued to see Brad from time to time, they lived in Los Angeles where Ashley worked for Forrester Creations.
Abby soon followed, much older, horse-loving and very sophisticated. In late January of , Brad died a hero after he pulled Noah Newman from the hole in the ice on the lake, when Brad fell through himself and drowned.
Abby was devastated by the news. Colleen was named the Trust-holder until Abby became of age. In , Abby's sister Colleen was kidnapped by Patty Williams, and she fell out of a boat and drowned. Colleen was buried next to her father Brad, her heart donated to save the life of Abby's father Victor Newman. Brad's mansion was inherited by Abby at Colleen's death. Abby began acting defiant to her mother in reaction to the deaths of Brad and Colleen, and blamed Ashley for losing Victor to divorce.
Convinced that everyone did what they pleased without consequences, Abby began looking for attention in guys too old for her, like Ryder Callahan. Abby expected to get her inheritances from Brad, Colleen, and Victor to finance it, but Ashley and Victor refused.
Abby began working on her uncles Jack for financing and Billy for exposure in his magazine, Restless Style. Abby Newman hired Rafe Torres to sue her parents. The day his divorce papers arrived, Daniel Romalotti fell into the conniving arms of Abby Newman. They made out in the Newman pool, and were caught still there the next morning by Nikki and Phyllis. As Abby begged them not to tell Victor and Ashley, a video of them had already been sent by Abby to her manager to publicize it.
Daniel covered her up and pulled her out, Ashley told her she was ashamed of her, and Katherine tossed her off the estate. She and Daniel did the semi-nude and suggestive shoot together, but Abby was livid when one of their milder photos made the cover, and her story had been bumped.
But it still got her a lot press, and convinced Daniel to do a nude painting of her. Jack stopped her from selling the mansion she was left by Brad and Colleen, and suggested that she use her number two Newman stockholder position as leverage. She tried, but Victor shot it down. Victor smashed the camera, tossed a robe over her, and told her it was not going to work. So she threatened to sell her million-dollar horse.
The club manager called the police and had Abby arrested. Abby was thrilled for the publicity, until she found herself stuck in jail four days awaiting her arraignment. But Daniel got Jack to bail her out. Abby informed her mother that the mansion where they lived was hers and kicked her out, so Ashley moved home to Abbott Manor.
She and Victor relented and gave Abby a substantial check from her trust, but she turned it down, demanding it all. Abby saw opening night for the new jazz club, Gloworm, as another opportunity for exposure. Abby hired Vance Abrams to sue Victor for mismanagement of her trust. Victor tried to dissolve the trust, but Vance had put a freeze on it. Abby dropped the lawsuit after seeing Victor have Victoria arrested on her wedding day to get what he wanted.
When she told Victoria about it, she joined Abby in the lawsuit, but Nick refused. He asked Victoria to return to Newman and offered to let Abby create an entertainment division for her reality television show. Saying they could not be bought and wanted to be independent, they turned down the offer. They went into mediation, and Victor made them another offer for half of what they had asked. But Victoria decided she wanted Beauty of Nature instead, Abby went along with it, and Victor turned them down flat.
At a stalemate, the judge ordered an audit of the Newman books to decide how much money had been mismanaged and if Beauty of Nature was a reasonable settlement. Victor refused and was about to be hauled off to jail, when they were stopped by attorney Heather Stevens, whose campaign Victor was financing. Heather said the case was being reheard by a higher court, and later confided in Victor that she hoped this favor would not reflect badly on her career and campaign for District Attorney.
Unfortunately for Heather, Billy Abbott found out and accused her on the Restless Style webzine of using her office to grant Victor favors, and she dropped out of the race in disgrace. Victor later lost the appeal, and his company financial records were seized.
Mark later connected Daniel with an important Chicago gallery owner who commissioned six new pieces. Just before they left for the party, Daniel showed Abby his final divorce decree which Amber had finally filed, and he thanked Abby for not nagging him to commit to their relationship, and keeping it just fun. But later at the party, Daniel admitted he was falling for Abby and wanted an exclusive relationship with her.
Daniel and Abby returned to his loft to find Daisy Callahan sitting inside in the dark. Even though Daniel was tricked, Abby and Daniel broke up over this, but they remained close as Daniel awaited the birth of his daughter, her adoption, and Daisy being sentenced to prison. Nick joined his sisters in their lawsuit against Victor for mismanaging their trusts.
Victor worked on Nick, telling him that if they won their lawsuit, Victor would be forced to take Newman public, they would only get a one-time settlement with no future profits, and they would no longer be a part of the company. Victor threatened that their legacy to their children would be that they destroyed Newman as a family business, and that hundreds of people would lose their jobs because of the greed of his children.
Desperate to make sure he did not lose the lawsuit, Victor convinced his other son Adam to claim that he had forged their new trust agreements during the time when Victor was supposedly dead and Adam had control of Newman. But Neil testified that when Adam was in charge at Newman, Neil had kept Adam from accessing anything that would have made the forgery possible.
The judge awarded Abby, Victoria, and Nick five hundred million dollars each, and ordered Adam arrested for perjury. Victor left with Michael, demanding that he find a way to overrule the judge's decision. The Newman children left to celebrate, but found it difficult when they realized and felt guilty that the verdict had come down on their father's birthday.
Abby called a press conference and stripped on camera for the occasion while he and Daniel watched admiringly. The police arrived, and Abby was arrested again. Ashley went to bail her out, but Victor beat her to it.
Abby showed up at the ranch later to thank Victor and apologize. But instead of accepting his children's settlement offer, Victor held a press conference to announce that he was taking Newman public.
Victoria and Nick were arranging to buy up stock, but Abby just wanted her settlement in cash. After repeated attempts to talk her mother out of marrying Tucker McCall, the day before their wedding, Abby got drunk and trashed the park which was decorated for the wedding before passing out in a fountain.
Awakened by police, Abby was arrested for vandalism. Victor and Ashley met Abby at the jail, and vowed to let her sit there as a lesson, but Tucker talked her into behaving herself, and she was released.
Later a rehearsal dinner was held at Gloworm, where Abby played nice to Tucker's face, but was hatching a plot to expose him as a philanderer to her mother.
She sent a text message to Diane Jenkins from Tucker's phone to meet him at the Abbott cabin, and one to Tucker from Malcolm's phone to meet him there for his bachelor party.
After the dinner, Abby, instead of driving her mother home, drove her to the Abbott cabin. When Ashley realized how drunk Abby was, she attempted to get her to stop the car, but in their struggle, Abby stepped on the accelerator just as Tucker was walking across the road, and he was struck by the car. Diane was behind them in her car and was first on the scene to tell the police what she had seen, an apparently drunk driver who appeared to purposely run a man down.
After Ashley and Abby were pulled from the wreckage, to protect Abby, Ashley told them that she had been driving. Tucker's condition was critical with a fractured skull and subdural hematoma. After surgery, Tucker lapsed into a coma. Ashley was fine, but Abby was still unconscious. Following Tucker's DNR instructions, the doctors took him off the ventilator, expecting him to die.
But his mother Katherine made Tucker breathe by shear willpower. Abby recovered and admitted to Ashley that she had set up Tucker and Diane to show Ashley that he was not worthy of her. Realizing that she had been the driver, Abby felt so guilty that she tried to confess, but was not believed. So Abby made a Naked Heiress video confessing that she had run down Tucker. Victor tried to stop it, and the tape mysteriously disappeared.
Abby went to Victor and offered to give him back her settlement money, hoping it would atone for all the havoc she had caused. Instead, Victor arranged for Abby to be admitted to a rehab facility in Connecticut. Abby had a surprise visit from Noah who told Abby that the attempted murder charges had been dropped against Ashley.
So Abby checked herself out and returned home with Noah. Abby attempted to get back together with Daniel, but he was no longer interested in being the exploited boyfriend of "The Naked Heiress". While Abby was in rehab, Ashley and Tucker were married in his hospital room without telling anyone.
During Jabot's national launch of its new cactus pectin product line and new Jabot logo which was held at Fenmore's, a reporter asked about their recent marriage, shocking the family and friends who had not yet been told. When asked, Abby covered by telling reporters that rehab had made her realize that her mom deserved to be happy. Victoria came up with the idea of using Abby's "Naked Heiress" persona as spokesperson for Beauty of Nature, Victor approved with the stipulation that she would keep her clothes on, but the idea was dropped when it was discovered that Abby's video confession of running over Tucker still existed.
Victor instead offered Abby a job learning the ropes at Newman. Instead, Abby announced to Ashley that she was going to finally grow up and return to college. Eventually Ashley reconciled with Tucker, moved back in with him, and made plans to marry. Abby agreed to be Ashley's maid of honor, and Jack walked Ashley down the aisle.
Abby stepped in for Ashley on a product promotion tour for Jabot while Ashley went on her honeymoon.
