Kristin Cavallari: Feuding with Lo

She’s always getting into it with someone, and this time Kristin Cavallari has beef with Lauren Bosworth.

While most of “The Hill’s” star’s problems have occurred around Audrina Patridge or Stephanie Pratt, off screen she and “Lo” are butting heads. “Kristin hates her," a source told.

"Lo has said some really nasty things about Kristin, and it got back to her. She's OK with most of the other girls, but she legitimately hates Lo."

And while Lo and Kristin have their problems, ex-frenemies Cavallari and Patridge now get along better than ever. The two may have been at it just for cameras over, Justin “Bobby” Brescia. A source says the two are actually friendly to each other and act like two good friends.

The source told, "Audrina and Kristin really get along. Kristin kisses up to Audrina! They don't have drama anymore."
