It's Britney Spears' Birthday! A Look At What's Next For Her

Spears, who turns 29 on Thursday (December 2), hints about new tracks.

Britney Spears remained relatively low-key in 2010. She was too busy recording her new album, a follow-up to 2008's Circus, to do much more than make an appearance on an episode of "Glee" dedicated to her.

As 2010 comes to a close, and Spears blows out another candle on her birthday cake — she turns 29 on Thursday (December 2) — fans are readying to hear some new jams from the pop princess.

In November, Spears' manager, Adam Leber, revealed that she would be recording a track with "... Baby One More Time" mastermind Max Martin, as well as fellow superproducer Dr. Luke, calling the tune a likely "smash." He also shared that the album would sound "progressive" and that ''it'll be a departure from what you've heard" in the past.

In mid-November, she tweeted about the Martin/Luke track, writing, "Just finished recording a monster with @TheDoctorLuke and #MaxMartin. Get ready..."

And Dr. Luke, while not specifying that he's referring to Britney, in a not-so-subtle hint tweeted last week, "Time to get this song out the door and out to mix.. I think you know what artist i'm talking Bout... Right???"

While not much has been confirmed about the album or when it might be released, several producers have talked about working on songs for the singer. "We can start one way and end up a totally different way. I really don't know," Danja said earlier this year. "I'm definitely gonna do my part and try to make it hard-hitting, up-tempo, high-energy. That's what I think we need, and that's what I'm gonna shoot for."
