Wearing a blonde wig, short denim skirt and pink bra, she treated the crowd to just five songs including Hit Me Baby One More Time and Toxic.

The mini-tour follows a tumultuous time - during which Britney has divorced aspiring rapper and father of her two young children Kevin Federline, had a series of run-ins with the paparazzi, shaved off all her hair and checked into rehab.

Britney’s dancer sings her praises - May 11 2007
A dancer who performed with Britney on her recent mini-comeback tour has been waxing lyrical about her time with the recovering star.

"She looks so good she should model," dancer Crisilla Crossland told the Las Vegas Review-Journal of Britney’s growing-out buzz cut, which is now apparently about 2in long.

She added that Britney even asked her dance troupe, "Would y’all cut your hair?" - though none of them apparently took the star up on her request.

The dancer also revealed that the singer is currently rehearsing two new songs, describing the new sound as "amazing".

Meanwhile, Brit, who performed four shows last week, has returned to the dance studio to continue her rigorous workouts.

Snapped in a pair of ripped fishnets, she’s been continuing to work on her performance at the Millennium Dance complex, and while her reps have declined to confirm any further performances, she doesn’t appear to be slowing down.

Pussycat Dolls founder Robin Antin, who saw her rehearsing last week told People magazine: "She’s been working really hard. She choreographed all of those shows herself. She’s such a talented girl."

Britney back on stage - May 2 2007
Britney Spears took to the stage in California yesterday, in what is believed to be her first public concert appearance in nearly three years.

Starting the five-song set at San Diego’s House of Blues with her classic Baby One More Time, Britney was back in top form. The boots-wearing one-time teen pop queen appeared on stage in a pink bra top and a short white skirt with her belly ring out.

The drama of the past few months appeared to be behind her.

Her only spoken words came as she was leaving. "Thanks everyone for coming," she told the packed club.

Earlier this year, the 25-year-old successfully completed a stint at a luxury Malibu drug rehab centre after a bout of headline-generating behaviour that included a February stop at a San Fernando Valley hair salon to shave her own head in front of television news cameras.

Yesterday Britney wore a long brown wig.

The Toxic singer filed for divorce in November from aspiring rapper Kevin Federline, just two months after giving birth to their second child, Jayden James. The pair also have an older son, Sean Preston, now 20 months.

The two reached a divorce settlement in March.

Her last concert tour ended in summer 2004. Earlier this year, Britney told fans of her plans for a hot career comeback.

"I look forward to coming back this year bigger and better than ever," she wrote in a January posting on her website, also noting she’s "been far from perfect".

Britney set to write sizzling book - April 27 2007
Britney Spears certainly has a few stories to tell given her recent behaviour, and it seems the singer could be set to write a sizzling autobiography.

The tell-all book will apparently spill the beans on what life was like for the singer when she was dating Justin Timberlake, according to America’s Star magazine, as well as dishing the dirt on her marriage to Kevin Federline.
