Boy Trouble for Kristin Cavallari?!

Kristin Cavallari definitely looked a little down as she arrived at the Brazilian restaurant Bossa Nova Brazilian Cuisine in Los Angeles yesterday and we're guessing it's probably because of boy troubles! Those of you who watch The Hills know that Kristin's been having a hard time with Justin Bobby and since he was the same with Audrina Patridge we suggest Kristin moves on!
