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 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 to appear in the dock in a $20 million defamation case over claims he accused DJ Samantha Ronson of being responsible for the cocaine found in Lindsay Lohan's car following her arrest for driving under the influence (DUI).
