Sarah Larson's relationship with George Clooney may have ended last month, but the gorgeous It girl tells E! that her budding modeling career is in high gear.

E! News caught up with Larson, 29, at the Lexus Style Villa Sports "Power of H" event Saturday night at the Hard Rock Hotel in San Diego.

Larson, who attended the party with a girlfriend after walking the red carpet solo, said she signed on last week as the face of a new ad campaign for designer Christian Audigier's line of couture dresses. "I just shot it a few days ago," Larson told E! "The shoot was very sexy and feminine. It was a lot of fun."

Larson, who earlier this year walked the runway at a fashion show during L.A. Fashion Week, explained why she was walking down Robertson Boulevard amid a frenzy of paparazzi on Thursday. "I was meeting with my agent and all of a sudden tons of photographers showed up. It was out of control."

Larson, who says she's splitting her time between Los Angeles and Las Vegas, wasn't offering up any insights into her split with Clooney, but at the party celebrating Lexus' line of hybrid cars, Larson revealed her Clooney-esque passion for environmental causes. "I'm looking to buy a hybrid so I wanted to check out some of the cars here," she said.

Larson was sipping champagne in the VIP area at the Lexus party near newly separated Dylan McDermott (he came with his two kids, no date), NFL'er Matt Leinart and actress Kate Walsh, who dined at Nobu inside the Hard Rock after spending the day watching Tiger Woods compete in the U.S. Open in nearby La Jolla, Calif.
