Kristin Cavallari & Nick Zano – It’s over!

Kristin Cavallari and Nick Zano are over. “They broke up,� a friend of Kristin’s reveals to Life & Style. “She moved out of their house. They’re going in separate directions.�

Kristin, 20, just moved in with Nick, 29, this summer. So what happened? “It wasn’t working out,� explains the friend. “She was bored, and I think she realized she was better off keeping her options open.�

“She used to be the It girl, and now she sees all of these other girls who would normally be in her shadow stealing the spotlight,� says the friend. “I think she wants back in on the scene. So get ready, Hollywood — here comes Kristin Cavallari again!�

“Living together put a real damper on things,� says a friend.
