Lauren Conrad and Kristin Cavallari know all too well that what happens in Laguna Beach doesn't stay there - but would they change anything about their time on the MTV reality show? "I don't necessarily have regrets," Conrad, 40, exclusively told Us Weekly while promoting The Reunion: Laguna Beach, which premieres on Roku Friday, April 10. "I think I was 18 years old on camera, so I'm definitely a little unsure of myself when I'm filming." Conrad pointed out that there's "actually not a lot of me talking" on the reality show, even though she was the narrator on season 1.
