Whats Britney doing with a rock on her ring finger?

Britney Spears has tongues wagging that she may be getting set for her third walk down the aisle after being spotted with a diamond ring on her engagement finger.

London, Sept 3 : Britney Spears has tongues wagging that she may be getting set for her third walk down the aisle after being spotted with a diamond ring on her engagement finger.

And her ring was not the only thing that the singer had people talking about as she partied in Vegas with Criss Angel, for another topic under hot discussion was the purple nightie that she hit the hotspots in.

One reveller said that Britney and the illusionist got pretty hot on the dance floor, with Angel even kissing her hand at one point.

"They danced and at one point he kissed her hand," The Sun quoted the onlooker, as saying.

While Criss Angel is currently going through a messy divorce, Britney already has two broken marriages under her belt.

Her first marriage to childhood friend Jason Allen Alexander on January 3 2004 at The Little White Wedding Chapel in Las Vegas set a new record when it lasted for just 55 hours.

Her second, to Kevin Federline in 2004, lasted for two years and two months, with Britney filing for divorce in November 2006.

The couple's divorce became final on July 30 this year. They are currently engaged in a custody battle over their two young sons - Sean Preston and Jayden James.
