Britney looked back to her best as she attended the Generation Rescue’s Event hosted by Jim Carey and Jenny McCarthy in L.A. on Saturday. Britney wore a short black dress showing off her sexy curves.

People.com: “She looked great and seemed really happy,” says a partygoer of the Snow Queen Vodka-sponsored shindig at the couple’s home in Brentwood. Though she kept close to her assistant Brett and didn’t speak to other guests, “She smiled and clapped during the video about autism. She was very into the information and watched a little bit of the dancers from Dancing with the Stars, sneaking out during one of the performances.”
