Kristin Cavallari Turns the Big 2-0

The former Laguna Beach actress Kristin Cavallari turned 20 recently, and celebrated at the grand opening of the new Hollywood hot spot Sideways Restaurant & Lounge.

The dinner included about a dozen friends, including actor Nick Zano (What I Like About You), whom she also spent New Years' Eve with. "He's a sweet guy," she said. "I'm very happy now. I'm in a happy place."

This celebration also happened to be on the same night that Britney Spears and her new boyfriend stopped by as well.

"This is the first time I've seen my friends [in a while] so I'm having the best time," Cavallari told People magazine. "I'm kind of getting over the club scene. I like this better because you can actually talk to someone instead of yelling at them. You can talk, eat food and just hang out with your friends."
