Britney Spears: 'Work Bitch' Singer Las Vegas Residency Deal Worth $15 Million?

Britney Spears' Las Vegas deal will be worth an estimated $15 million dollars, TMZ reported Monday.

The site allegedly got a hold of the financial details of Spears' two year contract with Planet Hollywood.  She will perform 48 shows a year and earn $310,000 per show. Celine Dion, who also has a Vegas residency, is paid $476,000 a show and is still the highest grossing star on the strip. However, the Work Bitch singer will get more time off and will be the centerpiece of the Planet Hollywood's desire to attract a younger audience.

There have been rumors for months that Spears will be performing in Vegas for the next few years but there has been no official confirmation from her camp. Insiders have said that will come within the next few days.

"She's so excited to perform and show what great shape she is in now," a source told The Las Vegas Sun. "She is mentally and physically 100 percent ready for the Las Vegas shows."

Spears  has been promoting her latest single, Work Bitch, which was released on Monday to iTunes.  She has sent out a series of tweets on the pop anthem that demands listeners work for what they want if it's a car or a hot body.  The song has already reached the Top 5 on iTunes.
