Celebrity blogger Perez Hilton has been hit with a $7.6 million copyright infringement lawsuit by a Los Angeles photo agency. Bosses at X17 claim Hilton, real name Mario Lavandeira, used 51 photographs without permission, payment or credit, including images of a pregnant Katie Holmes and Britney Spears partying.

X17 co-owner Brandy Navarre says, ""We've had trouble with a lot of bloggers. But he's the biggest, and the most arrogant and pigheaded about it, frankly. He is stealing our images and costing us money every day."

However, Lavandeira claims he has done nothing illegal, insisting, "I am going to vigorously defend myself. I am willing to step up to the plate and fight for my rights and fight for the rights of all bloggers."
