Is there something in the water? Us Weekly has learned that former Laguna Beach stars Lauren “LC” Conrad, 20 (now on spinoff The Hills), and Kristin Cavallari, 19, have split from their beaus.

 
Conrad confirms the split exclusively to Us. “Yes it is true, Jason and I are no longer together, but out of respect for his privacy I am not going to discuss the details of the breakup,” she says.
 
“Even though I am on a reality based show and I live much of my life in a fish bowl, I think anyone would understand that I need to keep some of my life private.”
 
Sources tell Us that it was Conrad who broke it off with boyfriend Jason Wahler. “He had been going out to clubs, flirting with girls, staying out late,” says a pal of Conrad’s.
 
“She wanted to focus on school and her career and was ready to move on. She feels really good about her decision.”
 
A second source adds she had a JASON tattoo covered up at the Hart & Huntington tattoo parlor at the Palms Casino resort last weekend when she and fellow Hills star Heidi Montag were visiting Sin City.
 
Meanwhile, a friend of Cavallari’s says that she and Brody Jenner, 23, split because “they fought a lot.” Jenner who works as a music producer with stepdad David Foster tells Us, “It was mutual.”
