Lily Allen stunned fans at an online album launch party in New York on Tuesday, yelling profanities from the stage and talking candidly about sex. The bawdy Brit was promoting her new release, It's Not Me, It's You, at the Bowery Ballroom as part of MySpace.com's Secret Show series.

Sipping white wine, the "Smile" singer kicked off the gig by poking fun at the Bowery crowd, stating, "You've been illegally downloading, you f---ers!" before launching into her new anti-George W. Bush anthem "F--- You" and urging fans to sing along with the chorus: "F--- you, f--- you very, very much."

Allen also performed another new tune, "Not Fair", which pokes fun at a former boyfriend who couldn't satisfy her after she performed oral sex on him.

She also took time to blast DJ Mark Ronson, who produced Allen's debut album, for not being part of the MySpace show.

She told the crowd, "Mark was supposed to f---ing be here tonight, but he's recording with some band in Brooklyn. He's too busy for me these days."
