Britney Spears has denied she's had liposuction.

The Toxic singer was rumoured to have had the treatment in Las Vegas on Monday to get her figure in shape for her pop comeback.

Britney's representative has denied the claims.

The star stayed at the luxurious Wynn resort with a girlfriend and several bodyguards.

Britney visited the pool on Monday but she stayed out of sight for most of the time in a cabana.

She then dined on sushi at Nobu in the Hard Rock Hotel and Casino, wearing an auburn bobbed wig, a straw cowboy hat and large sunglasses.

Meanwhile, Britney's relationship with her manager Larry Rudolph is said to be on the rocks again.

Britney and Larry parted ways shortly after she married Kevin Federline, but were reunited after she filed for divorce.

Rudolph encouraged her to go to rehab and allegedly ordered her friends not to take her calls on the night she shaved her head.

A source told Us Weekly magazine: "There is tension. He's been trying to get her help, and she doesn't feel she needs it.

"It is tough love."
