Kristin made a rare appearance during Heidi and Spencer's wedding this past weekend, and even managed to catch the bouquet for MTV cameras.
She's already in talks to guest star in six upcoming episodes of the hit reality show, the same show that Lauren doesn't want to be apart of after this season.
As you all recall, Kristin and Lauren guest starred on Laguna Beach together before Kristin left the show to attend Loyola in Los Angeles. She thought she was set for bigger and better things, but a few months later The Hills was created and Lauren became a huge star overnight.
Aside from a few hosting gigs, Kristin hasn't done much since her Laguna Beach days, so filling in for her archenemy Lauren on The Hills would be the ideal "role" for her.
Would you want to see Kristin fill in for Lauren once LC leaves the show? Or will The Hills crumble without their main star? Whether you love her or hate her, it's hard to imagine The Hills without Lauren.
