Get set for a possible reality TV catfight!

According to E! Online, Kristin Cavallari may be joining the cast of the MTV reality series The Hills, which might not sit well with her former Laguna Beach rival and current Hills star Lauren Conrad.

On the former show, the two girls were involved in a love triangle with series regular Stephen Colletti.

Although Cavallari has gone on to secure some acting work–recently wrapping the film Fingerprints, filming a guest spot on CBS’ Cane and is now shooting Spring Breakdown–it is her former rival Conrad who has found success with the popularity of the Laguna Beach spin-off, The Hills. MTV has issued a statement that they cannot confirm the reports.

But a source close to Cavallari says the former reality TV starlet is considering The Hills because “she feels like a loser every time she sees LC’s fame.”

“If Kristin goes on it, it will not be because she ‘wants’ to or because she misses the life of a reality star, it will be a business move,” says the source. “She needs to make a living, she wants to be rich and famous, and if she can use The Hills to make a bigger name for herself, she’ll grin and bare it.”

So tell us: Would you like to see Kristin Cavallari once again share screen time with former rival LC? –Karen Salkin
