Britney Spears made a surprise appearance at Jim Carrey and Jenny McCarthy’s Generation Rescue celebrity fundraiser to support autism this weekend where all eyes were on the sexy (yes, we said sexy) pop star.

An unbelievable transformation from her signature torn stockings and ass-bearing minis, the mother of two (who recently settled her custody case with ex-husband Kevin Federline) looked sexy and sophisticated in a figure-flattering black dress and plunging neckline.

Brit-Brit’s clothes weren’t the only transformation this weekend. The 26-year-old pop icon stepped back onto the scene with the complete package.   

Britney’s hair looked long, sleek and fabulous (the best we’ve seen in a very long time) and her makeup looked natural and glowing.

"She looked great and seemed really happy," a partygoer said of the recently transformed singer.

“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."

We are absolutely thrilled to see Britney bringing sexy back. She’s come a long way since her head-shaving, umbrella smashing days and we couldn’t be happier to see Brit back in style.

We know a comeback performance is in the works. And we can’t wait for it happen!
