Britney Spears ‘in Las Vegas bidding war’

Britney Spears is reportedly at the centre of a bidding war over her planned Las Vegas residency.

It has been claimed the American singer is gearing up to sign a $100 million deal which would see her perform regular shows in Sin City.

Originally, it was believed she would ink a contract with one of the Caesars Entertainment Corporation's venues, which famously owns the Caesars Palace Hotel & Casino.

According to TMZ, Britney has actually been approached by two establishments owned by the company with another unrelated venue also vying for her time.

If Britney's residency goes ahead, she will likely take to the stage several times each week. She will also be on hand to make guest appearance at special events held by the nightclub she chooses.

The site also claims reports the singer has already agreed a $200 million deal with a venue are untrue.

It's been suggested the 31-year-old singer is in line for a huge payday should the plan go ahead. Britney is expected to sign a multi-year deal which would see her net over $100 million annually.

Britney joined the US version of The X Factor for its latest series, but has confirmed she won't be back for a second round as she wants to concentrate on her music.

There has been some concern about whether she would be able to keep up with the rigours of a Las Vegas residency, after she was slammed for being bland on the TV programme. The star is also still the subject of a court-ordered conservatorship following her 2008 meltdown, leading to fears she might not be mentally fit enough for such a demanding agreement.

However, a source close to the star insists she is raring to go.

"She is well and has amazing family and friends who love her. She is dancing five days a week and is in the studio working on her eighth album. She is in demand career wise," the friend told MailOnline.
