Comedian Denis Leary stunned fans at the Fashion Rocks charity concert in New York on Friday by attacking Britney Spears, Ricky Martin and David Duchovny from the stage.

The Rescue Me star hosted the event which coincides with New York Fashion Week, and included performances from Beyoncé Knowles, Justin Timberlake, Mariah Carey and Rihanna. And Leary left the crowd speechless with a foul-mouthed tirade, mocking Spears' recent breakdown; Martin's newborn twins; and ridiculing Duchovny's stint in rehab for sex addiction, reports the New York Daily News.

He told the audience, "Britney Spears will not be here tonight but we're gonna do a little Britney tribute later on. I'm gonna chug a bottle of NyQuil, do seven shots of vodka, shave my head and make out with members of the paparazzi and then I'm gonna leave my kids with Lil Wayne for about three and a half weeks."

"Ricky Martin will not be here tonight. He just had twins today. Surrogate mom. Yeah, they had to do it that way because babies don't come out of other men's @#%#."

"David Duchovny will not be here tonight. I think you know why. I don't really buy the sex addiction thing. Do you? If sex is an addiction, I might as well have my own wing at the Betty Ford Center."

All proceeds from the star-studded event will go to the Stand Up 2 Cancer charity.
