Kristin Cavallari Keeps Warm

Kristin Cavallari tries to keep warm with a hoodie and scarf outside Villa Lounge nightclub in Hollywood late Friday night.

Recent reports suggest that the former 20-year-old Laguna Beach star may be joining the cast of The Hills. Exciting!

Hey, anyone else curious as to what Kristin did with her Nick Zano tattoo? She had his initials NZ tattooed onto her left wrist!
