Crack is whack yo. Just ask Tatum O’Neal, who was arrested last night for allegedly buying coke and crack in NYC from a homeless man. She was busted just blocks from her apartment.

According to a source, she was caught at 7:30 pm. When the cop approached, she said, “You know who I am right?”

Tatum then told police that she was “researching a part.”

The cop was probably all like, yeah I seen you blowing a guy last week for a smack. You sure research the hell out your role. Cracker!
