One of the darkest chapters of Paris Hilton's life was the infamous 2003 leak of a sex tape featuring her and then-boyfriend Rick Salomon. So she was a little upset when she found out her friend Brooke Mueller was still friends with Salomon on 'The World According to Paris' (Wed., 10PM ET on Oxygen).

Hilton said she equated some of her current insecurities to that leak, at which point Mueller was a little taken aback.

"I totally thought you were involved," she said, after admitting her ongoing friendship with Salomon. Mueller was not only under the impression Hilton was involved in the leak, but thought she'd raked in half the earnings as well.

"I just wanted it to be forgotten," Hilton said. "I can't believe you're friends with him!" But considering Mueller was married to Charlie Sheen, and all the things he's done, should it really be a surprise she'd be friends with someone who'd leak a sex tape?
