Britney Spears spent $3,000 on candy in one afternoon.

The 'Womanizer' singer splashed out the staggering sum at the Sugar Factory, which is located inside Las Vegas' Mirage hotel, which she visited with sons, Sean Preston, four, and three-year-old Jayden James, and boyfriend Jason Trawick on Sunday (27.09.09).

A source said: "She spent about $3,000 and walked out of the store with 10 bags. She got a bunch of candy and shirts for her kids and got a bunch of the couture lollipops to give to her back-up dancers."

Among the items Britney, who was in Las Vegas for the final US show of her 'Circus' world tour, bought were a box of Sugar Factor milk chocolate and 25 $25 lollipops.

After paying for the items the store sent another $2,500-worth of candy to Britney's room at the Mirage.

Britney pulled out all the stops for her final American show.

Barry Manilow and pop star Lance Bass were in the audience, and Britney spiced up the routine to 'Breathe On Me' by singling out Lance for a sizzling lap dance.

She also performed at Las Vegas' Mandalay Bay Hotel and Casino on Saturday (26.09.09), as former Spice Girls star Mel B and 'Hannah Montana' actress Miley Cyrus looked on.
