NEW YORK (Reuters) - Music label Zomba said on Thursday it has sued gossip Web site PerezHilton.com for illegally posting recordings by pop singer Britney Spears.

The suit, filed in U.S. District Court in Los Angeles Thursday, accused the Web site and its proprietor, Mario Lavandeira, of illegally obtaining and posting at least 10 completed songs and unfinished demos from Spears's upcoming album "Blackout" during the past three months, Zomba said in a statement.

"Blackout" was scheduled to be released on Nov. 13 by Jive Records, which is part of Zomba Label Group, Zomba said in a statement.

The suit does not specify the amount of monetary damages that Zomba is seeking, but asks for real and punitive damage as well as legal costs. Zomba owns the copyrights to Spears' recordings.

Spears is not a party to the lawsuit, Zomba said.
