Britney Spears' comeback stalls

The 26-year-old, was set to be perform new material under the stage name of M&M.

She was due to perform at three House of Blues venues in San Diego, Anaheim and LA reports Metro UK.

Just days ago, Britney Spears canceled a secret show at the Forty Deuce strip club in LA last Wednesday.

A spokesman for the club said: 'She wants to get back to performing on a small scale before she gets back in front of a big crowd.'

Meanwhile, Britney Spears has been out on a date with the rock singer she met in rehab.

The 'Toxic' singer and Howie Day dined out at Hollywood's The Bridge restaurant - one of Britney's favorite eateries - and then visited nightclubs Element, Les Deux, Parc and finally Teddy's where they partied on Saturday night (29.04.07).
A source told website X17online: "They made a handsome couple. They left the club and Howie drove Britney's Mercedes back to her house and stayed there all night."
Britney was wearing a lace vintage-style long sleeve mini-dress, brown fedora hat and brown cowboy boots and a new long, dark wig.

The couple met at Malibu's Promises center where Britney was being treated for alcoholism and alleged post-partum depression.

The 25-year-old mother-of-two played tennis with Howie during her stay at the center and the pair were also allegedly caught frolicking in the bushes.
