Lauren has already said she won’t be returning to the show, and Kristin has reportedly signed on for six new episodes.
She already made an appearance at Heidi and Spencer's wedding, and even managed to catch the bouquet.
MTV was originally worried that their hit show was going to suffer after Lauren left, but her archenemy Kristin has her claws out and is ready to take over as the star of the show. In fact, she thinks she "do it better than her."
What are your thoughts? Do you think Lauren is replaceable?
