Good lord ... I had no idea Tatum O'Neal was on crack!

As you've probably heard, the actress/daughter of Ryan O'Neal/ex-wife of John McEnroe was busted for buying cocaine and crack last night near her Lower East Side apartment!

And here was the excuse she gave the cops, according to the New York Post:

    "You know who I am, right?" Then she said, "I'm researching a part - I'm doing this for a part as a junkie. Can't we just forget about this?" !!!!


She was charged with criminal possession of a controlled substance. -- Yikes!!!
