Though nothing’s confirmed from the horse’s mouth, some believe Brit’s Sin City residency will earn her a cool $200 million for two years.

It is thought she’ll perform at The Colosseum at Caesar’s Palace, a stage home to Elton John, Shania Twain and Celine Dion. But will the big paycheck earn Vegas big bucks?

“She has a narrower appeal” than, say, a Dion, one music business expert tells Eonline.com. But then again, it would be a “good look” for whoever lands the Britney deal… in other words, a publicity coup worth paying extra for.

Experts believe Britney could pull in $2 million a week. Multiply that by 40 weeks a year for several years, and you’re looking at a gold mine.

“Deals such as this are based on scale,” says Daren Libonati, president and COO of the promotion and production company Justice Entertainment Group. “That’s a very basic guess on what such a deal might look like. It could be even more.”

“It’s good branding for whoever signs with her.”
