Kristin Cavallari and Brody Jenner Split

Kristin Cavallari, 19, and her boyfriend, Brody Jenner, 22, have split, People magazine reported. "Yes, Brody and I broke up," Cavallari says. "It's just hard right now because I am working all the time. We're still good friends though." In between spending time with Jenner, Cavallari was spotted several times with Nick Lachey, but friends told the magazine at the time the relationship was "not anything serious." Cavallari, who shot to fame on Laguna Beach: The Real Orange County, recently wrapped her film Fingerprints, and is now shooting Spring Breakdown, both slated for release next year.
