Britney Spears put on a smile as she left the recording studio last night. She's been hard at work on that new album she's so excited about, and the rumors of a possible duet with Justin Timberlake keep popping back up. While I'm still a bit skeptical that would ever happen, there are a lot of Britney and JT fans out there who would love to see the famous exes collaborate for a track. Until there's more definitive news on that end, we're still holding out hope that Brit will go from her hilarious VMA promos to an awesome VMA performance. They're adding more acts all the time, including the newest announcement that Pink will be taking the stage to sing "Say What"! Fingers crossed the next big announcement includes Miss Spears.
