Britney Spears' record label Zomba has sued celebrity blogger Perez Hilton for illegally posting tracks from her forthcoming album on his website. The company claims Hilton - real name Mario Lavandeira - illegally obtained and uploaded at least 10 completed songs and incomplete demos from new LP Blackout onto the site. The copyright infringement lawsuit was filed by Zomba - which owns the copyright to Spears' recordings - on Thursday (11Oct07) in the U.S. district court in Los Angeles, but does not specify the amount of monetary damages being sought. Zomba has confirmed Spears is not a party in the case. It comes just a day after Lavandeira was the subject of a court summons (10Oct07) to appear in the dock in a $20 million (GBP10 million) defamation case over claims he accused DJ Samantha Ronson of being responsible for the cocaine found in Lindsay Lohan's car following her (May07) arrest for driving under the influence (DUI).
