Paris Hilton's Boyfriend Thinks She Looks "Really Hot" in New Movie

Paris Hilton's rocker boyfriend Benji Madden told her she looked hot even with prosthetics to make her look ugly.

The hotel heiress, 27, was uglified for scenes in her new movie Repo! The Genetic Opera. But when Good Charlotte star Benji saw her new look on screen for the first time he still thought she was sexy -- warts and all.

Paris says, "The looks were pretty brutal at points. I was pretty embarrassed by all the prosthetics on my face. In every scene I look completely different.

"Throughout the film I had different prosthetics, different hair, different eyes, and different chins. But Benji thought it was really hot!"

Meanwhile, Paris is being sued for allegedly failing to promote her 2006 movie National Lampoon's Pledge This!

Producers Worldwide Entertainment Group claim the socialite didn't fulfill her publicity duties causing the flick to flop.

They are looking for almost $80k in damages, according to papers filed at the US District Court in Miami.

Paris was paid $1m for the role and to carry out "reasonable promotion and publicity".

But she is said to have fallen out with the producers over the amount of nudity in the comedy.
