"Britney Spears has been a great success for the company and will be extended, if she wants to do it, and I cannot see why not," Caesars Palace President Gary Selesner said during the Vegas Uncork'd by Bon Appétit Master Series dinner with Bobby Flay and Giada De Laurentiis.

"She has been filling out the place every night, and she is enjoying it and is in good health."

Selesner added that Spears is enjoying life in Sin City, "She has a good life, coming in on private jet," he said.

"She has a villa upstairs at Caesars and really enjoys it here - so why wouldn't she stay?"

The $12 million offer appear more remarkable given Spears lip-syncs her way through her 90-minute performances. However, fans are only too happy to shell out up to $300 per ticket. 

But her lack of singing hasn't put off punters who shell out up to $300 to see the ex-teen idol shake her body.

Selesner admitted that his company took a "gamble" in inking the original deal, which apparently pays Britney $30 million over two years.

"You just didn't know what was going to happen.But the fans loved her. And she has so many fans from all over the world, that the support has been fantastic."
