Meanwhile, fans can't wait for Britney Spears to make her big comeback, but it seems the recently rehabilitated 25-year-old isn't quite ready to take to the stage again. She reportedly got cold feet and canceled a show at an LA nightclub last week, deciding she needed more time to rehearse.

"She came on stage during rehearsals, looking very hot, with four back-up dancers and sang three songs,"

"They ran through the set several times, the choreography was smokin', and she sounded great," say the nightclub's owner

“She wants to get back to performing on a small scale before she gets back in front of a big crowd,�? according to a source, who says the singer apparently thought that the club, which is known for its burlesque shows, would be a good place for her first post-rehab appearance reports MSNBC.

The current buzz is that Spears will make a surprise appearance at one or more House of Blues in Southern California this week.
