Caesars Entertainment is in talks with Britney Spears for a Planet Hollywood residency in Las Vegas.

The 'Toxic' singer - who called off her engagement to Jason Trawick and quit her role on 'The X Factor' last month - has been approached by several venues for an extended residency in the city and Caesars Caesars Entertainment spokeswoman Emily Wofford confirmed negotiations are ongoing.

Britney has hinted at a Las Vegas deal, replying to a recent tweet from her dog Hannah's Twitter account which read ''Mommy, are dogs allowed to gamble in vegas? Gonna cash all my bones in for chips.'' with a ''I don't think so honey #VivaLasVegas (sic).''

Her manager Larry Rudolph has also spoken about the residency, saying: ''We are in deep negotiations and I'd be shocked if it didn't happen. Hoping to have a deal done very soon.''

However, friends aren't sure the 31-year-old singer will cope and believe she would be happier at home with her sons Sean Preston, seven, and Jayden James, six.

A source said: ''I'm not sure just how good an idea Vegas is for Britney right now. If she can't handle 'The X Factor' - how will she be able to perform five days a week in Vegas?

''She's a homebody, she loves her sons and has her daily routine. At this time, she may need to concentrate on her health and happiness - not rebuilding her career.''
