Britney Spears Las Vegas Comeback Is Off?

It looks as if Britney Spears may not be heading to Vegas after all.

Rumours of a Sin City performance emerged earlier this month, after the singer was spotted dining with Palms Hotel & Casino owner George Maloof Jr. in Los Angeles.

However, her former manager Larry Rudolph – who patched up his relationship with the singer earlier this year - has refuted reports she is in secret negotiations to stage a major comeback spectacular in Las Vegas.

He tells the Las Vegas Review Journal, "She's not here (in Las Vegas) and she's not coming in. I wouldn't lie to you."

Yesterday a Los Angeles court heard that Brit is still incapable of participating in any legal proceedings, with her attorney telling the court that her doctor hopes to carry out "additional testing in the not-too-distant future".
