Britney Spears is bound for Las Vegas, with the former teen pop star set to perform dozens of shows over the next two years.

Spears, 31, announced her forthcoming two-year residency at Planet Hollywood Resort & Casino during an early morning TV appearance today.

"I'm definitely ready," she told ABC's Good Morning America, adding that she has been training for five hours a day in preparation.

The upcoming show, entitled Britney: Piece of Me, will debut on Dec. 27. Spears said it would be action-packed, high-energy and combine her greatest hits with her latest material. The former Mouseketeer, who debuted as a singer at the age of 16, is known for songs like ...Baby One More Time, Oops! I Did It Again, Toxic, Womanizer and Gimme More.

Altogether, she is slated to play 50 shows a year in 2014 and 2015.

The Las Vegas gig puts the performer in good company: in recent years, top stars such as Shania Twain, Céline Dion and Elton John have drawn huge audiences for their long-running residencies.

Spears is also set to release her eighth, as-yet-untitled album on Dec. 3, just ahead of her start in Las Vegas. The album's first track, Work Bitch, was released this week.
