With the custody case finally behind her, Britney Spears took time out Saturday night and surprisingly attended Jenny McCarthy and Jim Carrey’s fundraiser for Generation Rescue, an organization dedicated to researching autism.

“She looked great and seemed really happy,” says a partygoer. 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.’

The charity event was sponsored by Star Queen Vodka and was hosted at Jen and Jim’s house in Brentwood, CA. For entertainment, the Dancing With The Stars dancers performed a couple numbers and of course Jim Carrey had to get on stage to give the guests a good laugh.

Also at the bash were newlyweds Charlie Sheen and Brooke Mueller, as well as Robert Rodriguez and Rose McGowen, who apparently were seen kissing and dancing all night.
