Tatum O’Neal Hitting The Bottle Again!

It may have all been wine and roses for troubled Tatum O’Neal once she hooked up with funnywoman Rosie O’Donnell — but that’s the last thing she needs!

The 51-year-old has “fallen off the wagon- — not good for someone who has been in rehab at least three times and is in AA,” a source told The National ENQUIRER.

Tatum, who memorably won an Oscar as a child star, has battled drug and alcohol problems for years, and was reportedly sober before she began dating the former roly-poly “View” co-host, who is going through a nasty divorce and custody battle.

An exclusive photo obtained by The ENQUIRER showed glasses of red wine in front of Tatum when she and Rosie attended an intimate dinner out at New York City celebrity restaurant Da Silvano in August.

The source also claimed Tatum was spotted guzzling more red wine over a meal with a pal at Zinque, a restaurant in West Hollywood on Sept. 24.

“I was surprised to see Tatum tossing back at least two glasses of red wine,” the source told The ENQUIRER. “You think Tatum would have learned her lesson.”

Due to her cocaine and booze addiction, Tatum lost custody of her and ex-husband John McEnroe’s three children in 1998, years after their 1994 divorce.

While she appeared to clean up her act, she was arrested in 2008 after police witnessed her giving money to a street drug dealer on Manhattan’s Lower East Side.

Added the source: “No one wants to see Tatum as a fall-down drunk and junkie again. She needs an intervention and she needs it now.”
