BRITNEY SPEARS' Las Vegas residency is on, according to her manager LARRY RUDOLPH.

News of the pop star's Sin City run of shows has been swirling around online ever since she announced her decision to step down as a judge on America's The X Factor, and now Rudolph has confirmed to U.S. programme Extra that the residency will take place at one of two casinos, one of which is Caesar's Palace.

He insists the deal will be finalised once Spears' team decides which one to go with.

A formal announcement is expected in the coming weeks.
