VIDEO: Are K-Cav And LC Still Hatin' On Each Other?

She may have implied that watching Lauren Conrad on The Hills is like throwing back shots of Nyquil, but Kristin Cavallari swears that she and LC are otherwise over all that drama from their Laguna Beach days. (Stephen Colletti was sooo high school!) Hear what else K-Cav told Ryan Seacrest on his morning radio show, then watch an interview with Speidi (via last night's The Hills: Live After Show) for the scoop on the happily married couple's new side hustle. (In case ya hadn't heard -- which is kind of inconceivable -- Spencer and Heidi will be co-starring on NBC's Survivor-esque competition, I'm A Celebrity, Get Me Out of Here! First big challenge: parting ways with their BlackBerries ... and hair products!)
