After finishing the British leg of her world tour Britney Spears took a well-earned two-week break.

But it appears that the holiday has had an impact on her figure - with Britney looking distinctly fuller-figured as she took to the stage in Paris.

The singer's thighs and arms looked larger than before - although that won't last for long.

With night-after-night of concerts lined up the 27-year-old is bound to soon be back in shape.

Last night she performed a series of energetic dance routines as she appeared onstage for the first time since dyeing her hair brunette.

She also unveiled a new selection of sparkly body-baring outfits. On her Twitter page Britney wrote: 'New leg, new song, new outfits, new do....'

Following her spell in the UK Britney returned to Los Angeles, and stayed out of the spotlight as she relaxed with three-year-old Jayden James and Sean Preston, two.

Britney is currently enjoying being with her sons after being forced to spend lengthy times apart during a rocky 2008 when her ex-husband Kevin Federline was given custody of the boys.

However, under a recently agreed custody deal, Britney will now care for her sons for over 50 per cent of the time during the summer.

While Britney is on stage for her Circus tour, which returns to North America after the European leg wraps on July 26, Kevin will accompany her to care for the children.
