Nina Dobrev, Ian Somerhalder, Rachel Zoe Pictures at John Varvatos Stuart House Benefit

Nina Dobrev and Ian Somerhalder were together in LA for Sunday's John Varvatos Stuart House benefit, which raises funds for the rape treatment centre at Santa Monica-UCLA hospital. Dave Matthews performed, and Leslie Mann co-hosted a silent auction with husband Judd Apatow. The annual event also brought out Hollywood couples like a loved-up Cindy Crawford and Rande Gerber, as well as Rachel Zoe and Rodger Berman. Rachel and Rodger made the rounds with their almost 1-year-old son Skyler, who celebrates his first birthday on March 22. Zoe Saldana also turned out during a break from shooting Star Trek, as did Harry Potter's Tom Felton with girlfriend Jade Olivia, and True Blood hottie Joe Manganiello.

Nina and Ian are in California during a break from working on The Vampire Diaries in Atlanta. The Vampire Diaries cast was at Paley Fast on Saturday, but Ian's highlight on Sunday was meeting Alice Cooper. He tweeted about the magnitude of meeting his former idol, writing, "What a weekend . . . I use to air guitar that dude when I was a youngster." Nina, meanwhile, had another connection to Rachel Zoe. At the Paley panel, Nina donned a black dress from the Rachel Zoe Collection.
