Other movies in which O'Neal appeared include The Bad News Bears, Nickelodeon, International Velvet, and Little Darlings. She appeared as the title character in the Faerie Tale Theatre episode Goldilocks and the Three Bears. Her acting career took a backseat to her marriage to John McEnroe, the professional tennis player, for many years, but in 2005 she began a recurring role as Maggie Gavin on the firehouse drama series Rescue Me, portraying the unbalanced and lively sister of Tommy Gavin, played by Denis Leary. O'Neal's character is married to a firefighter in her brother's firehouse.
In January 2006, she participated in the second season of ABC's reality series Dancing with the Stars but was eliminated in the second round. She went on to do commentary for the series on Entertainment Tonight.
From 2006 to early 2007, Tatum starred as the vindictive and psychotic Blythe Hunter in the My Network TV prime-time drama Wicked Wicked Games. She appears opposite Nashawn Kearse and Vanessa L. Williams in the Liberty Artists feature film My Brother (2007).
O'Neal writes in her autobiography that when she was 13, her father took her and her friend Melanie Griffith on a trip to Europe, where she caught him having sex with Griffith in their hotel room. She also claims that when her father left for a movie shoot, she smoked opium with Griffith and then invited a male hairdresser and his girlfriend to their hotel room where the four of them participated in an orgy that Griffith had dragged her into.
Also in her autobiography, O'Neal says she had a brief makeout session with Michael Jackson, who left because he got too nervous. He told the press, years later, that she was his first love. They continued a relationship that ended in 1979 when her manager told her it would be unacceptable for her to be with a black man.
In 1986, O'Neal married tennis superstar John McEnroe. No one from her family attended the ceremony. The couple had three children: Kevin, , Sean, , and Emily, , then split in December 1992 and divorced in 1994. Following the divorce, O'Neal's drug problems re-emerged and she developed an addiction to heroin. As a result of her drug problems, McEnroe obtained custody of the children in 1998. On June 1, 2008, she was arrested for allegedly buying crack cocaine near her Manhattan apartment building. When police searched her, they allegedly found two bags of drugs—one with crack, one with regular cocaine—and an unused crack pipe. She was charged with a misdemeanor, criminal possession of a controlled substance. Authorities released her without bail.
On July 2, 2008, O'Neal pleaded guilty to disorderly conduct in connection with the arrest and agreed to spend two half-day sessions in a drug treatment program. If she completes those sessions and pays a fine by September 4, 2008, the charge against O'Neal will be dismissed.
