Britney Spears has been a dance class fanatic since leaving rehab, but so far, she's kept fans guessing about when she'll make her big comeback performance.
The mystery widened when the head case and commando queen reportedly pulled the plug on a show in Los Angeles late on Wednesday night.
The mother of Jayden James was expected to take the stage with her band, the M & Ms, at the hip L.A. club Forty Deuce, where she infamously swapped costumes with dancers in December, but Brit failed to show.
On the club's website, boss Ivan Kane says:
"[Britney Spears] 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."
But Spears decided that she needed more time to rehearse for her comeback show, leaving devotees hanging.
A handful of semi-secret shows are lined up for Los Angeles next week, so stay tuned... unless the former Mrs. Kevin Federline nixes those too.
In other Britney news, Star magazine is reporting another possible business collaboration - this time with booted American Idol joke Sanjaya Malakar.
The magazine claims Britney Spears is eager to work with Idol's hair-raising, tone-deaf sensation. Now that's a good way to resurrect an ailing career.
"Britney started watching American Idol when she was in rehab," Star quotes a source. "She became a huge Sanjaya fan and thinks the two of them can make beautiful music together."
Just give us a nude Shyamali Malakar strumming a guitar, thanks. Sounds to The Gossip like Sanjaya planted this idea in the press in an attempt to eke out a 16th minute of fame.
