Dozens of protesters representing People for the Ethical Treatment of Animals (search) greeted Jennifer Lopez at the premiere of her new movie "Monster-in-Law" (search) with signs declaring her the "monster-in-fur" for her Sweetface fashion collection.

The protesters, who included some people dressed in animal suits, complained that they have asked several times that Lopez eliminate fur from her clothing line, but have been ignored.

"She could make a difference in a positive manner, and what she does is cause the death of a lot of animals," protester Linda Kraemer said during Friday's demonstration in front of the National Theater in Westwood.

Lopez was asked what she thought of the protesters.

"I don't," she replied as she headed into the premiere.

Others involved in the film said the demonstration didn't bother them.

"It's America. You have a right to protest and do whatever you want to do," said actress Wanda Sykes.
