Zomba sued PerezHilton.com for copyright infringement on Thursday. The recording group says the gossip Web site illegally posted recordings by pop singer Britney Spears. Zomba claims Perez illegally obtained and posted at least ten completed songs and unfinished demos from Brit’s Blackout LP.

On Wednesday, Jive Records moved up the Blackout U.S. release date to October 30th and the international release a day earlier because some recordings had been leaked online.
