Kristin Cavallari sported a Bebe skirt and shoes as host of yesterday's fashion show featuring the line's spring/summer 2008 collection. Thrown by the Beverly Hills Women's Club, the show raised funds for the Make-A-Wish Foundation. "I hosted a Bebe fashion show when they did the Make-a-Wish Foundation event a few months ago," Cavallari told TV Guide. "I loved it so much, when they asked me to come back it was a no-brainer." The shoes showed off the actress' gams, which she's been fine-tuning for an upcoming film. "I'm working with trainer Mike Alexander, who has me doing tons and tons of lunges," she divulged. "Apparently, they burn the most calories." Beyond workout secrets, Cavallari let TV Guide in on other areas of her life that have drawn media speculation - among them, the rumor that she'll be appearing on The Hills. "Not true," says the actress. Then there's the buzz about her dating Kevin Connolly of

Entourage fame. "No, not dating him," she clarifies. "I just worked on a short film with him." And her dating status? "Single. Having fun." She has found some actors riveting of late, though, especially the cast of Spring Breakdown, an upcoming comedy starring Parker Posey, Amy Poehler and Amber Tamblyn, along with Cavallari. "From a comedy standpoint, they were the best people to be thrown into situations with," she says of the cast. Though the Laguna Beach star has recently been celebrating turning 21, overall, she says, "My life's been pretty boring." - Bekah Wright More party coverage: " Will Ray Romano Deal Us a New Sitcom?
