Looks like Kristin Cavallari is back on the market after finding out her boyfriend, nightclub owner Sam Nazarian had been cheating on her! She busted him with her own eyes.

“Kristin had left a ring over at his house so she decided to pop over to pick it up on Thursday afternoon. Sam was working but she has a key.”

“Kristin made her way to the bedroom to retrieve her belongings and that’s when she saw a striking brunette exiting Sam’s bathroom. She knew right away what was going on. She asked the girl who she was and they bonded immediately. She called Sam from her phone but then she had the other girl talk to him, so he was so freaked out. He was expecting Kristin’s voice and then he got the voice of the girl he was cheating on her with!”
