The Simple Life Returns Sunday

The reality-style series, which shows how inept the two celebutantes can be in everyday situations, returns Sunday, 10 p.m. EDT on E!

Hilton characterizes the two as "complete opposites."

"I'm the nice one, she's the evil one," the baby-voiced blonde says. "Some people change when they think they're a star or something and some people stay the same. I've always been the same and she's definitely not."
