Source: Bang Showbiz NewsBritney Spears is at the centre of a bidding war for a Las Vegas residency.The 'Scream & Shout' singer - who is said to be close to agreeing to a $100 million, one-year residency with the Caesars hotel chain - has now received big money offers from two rival hotels in the US gambling capital, reports TMZ.com.By agreeing to a deal, Britney would perform a complete live show several times a week for hotel guests, much like fellow songstress Celine Dion, whose Vegas residency is worth $100 million.However, it's reported that the former 'X Factor' USA judge could potentially command an even bigger fee than the 'My Heart Will Go On' hitmaker, because she's expected to be a bigger draw.Meanwhile, friends of the 31-year-old pop superstar have expressed concern about how Britney - who last week announced she had split from fiancé Jason Trawick - would cope with the demanding schedule of a residency.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."At ['X Factor'] auditions, Jason would calmly escort Britney by the hand back and forth to her seat during breaks. He was there for her."
