London, Aug 4 : Pop diva Britney Spears has gone for a makeover with a new blonde look.

The Toxic singer last night stepped out with her blonde hair and a short black dress.

She went to the Grand Star Jazz Club in LA and displayed plenty of sex appeal, reports the Sun.

Meanwhile, Spears'' ex-husband Kevin Federline has apparently confirmed the singer''s budding romance with her agent and insists he's pleased that his ex-wife has found a stable relationship.

The 28-year-old star, who divorced Federline in 2006, has recently been rumoured to be going around with her long-time agent Jason Trawick. (ANI)
