Britney Spears announces two-year Vegas show

It's Vegas, y'all!

Britney Spears has officially booked a two-year residency at Las Vegas Planet Hollywood, the "Work Bitch" singer announced Tuesday.

"Britney, Piece of Me" will be part club, part theatrical show, with a mix of her greatest hits and new songs.

"We wanted the environment to be that way so people could come and have a good time and stand up and feel like they're in the show with me," Spears said. "I love Vegas. The energy here is really, really good."

While the show, starting December 27, will include 50 performances, Spears said she hadn't yet decided if she would make the move to Vegas full-time.

Her new, as yet untitled album, will be released December 3.
