Long-ignored actress Sean Young has joined the parade of celebrities going to rehab, more than a year after Brit and LiLo made it cool. Despite last making headlines for failing in her efforts to sneak into Vanity Fair‘s 2006 Oscar party, she somehow made the cut to attend last weekend’s Director’s Guild Awards for what will likely be the last time. Young got tanked and heckled nominee Julian Schnabel to hurry the hell up with his speech so that they could get to the winner and/or back to the bar. She was escorted out, and her “representatives” notified the press today that she is a well-known alcoholic now seeking treatment.
