Having already filmed a sex tape with Laurence Fishburne's daughter, porn star Brian Pumper has now moved on to Beyonce, and is dissing Jay-Z in a new song called "She Ain't Satisfied," spitting "Get out of here, she tired of you, yo sex game weak/ You ain't lick coochie right, you ain't packin' no meat/ You ain't the man in the bedroom, you don't know what you doing/ You ain't ill with the pipe, you ain't sick with the screwing." Daaaaaaamn son. [HipHopWired]

So Ke$ha has a new video. "It's my favorite video, I think, ever, that I've done because I get to get really dirty in glitter [and] sand, and we all get naked because we're just, like, taking it all off," she told MTV. "It's also about taking off your inhibitions and being raw and real. And then we start tearing each other apart into pieces, and we're all made out of glittery magic dust...stardust." That's actually my nightmare. [MTV]
