Kim and Kourtney Kardashian stopped by The Wendy Williams Show to dish on boyfriends, love, hair and music careers.

Kim tells Wendy about her new boyfriend, New Jersey Nets star Kris Humphries, saying, “He’s a really good guy, and I think that for once I’ve really taken my time with [the relationship], I’ve know him for months and have definitely tried to keep it low key.” But she stays tight lipped on the physical side of their relationship. “I don’t kiss and tell,” she says.
