Washington, February 12 : British singer-songwriter Lily Allen's fans were left stunned upon hearing her yelling profanities from the stage, and talking candidly about oral sex, when she launched her new album with an Internet gig in New York on Tuesday.

She was promoting the album titled It''s Not Me, It''s You at the Bowery Ballroom as part of MySpace. com's Secret Show series.

According to reports, Lily sipped white wine, and started the show by poking fun at the Bowery crowd

"You've been illegally downloading, you f**kers!" before launching into her new anti-George W. Bush anthem F**k You and urging fans to sing along with the chorus: "F**k you, f**k you very, very much," Contacmusic quoted her as saying.

The website further revealed that Lily even performed `Not Fair', which pokes fun at a former boyfriend who could not satisfy her after she performed oral sex on him.

The singer also slammed DJ Mark Ronson, who produced her debut album, for not being part of the MySpace show.

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