Britney Spears Smoking Body

Britney Spears has posted new photos on her website of her working on her dance moves in preparation for her world tour, which kicks off March 3 in her home state of Louisiana.

Two weeks ago, we saw a sneak peak of her rehearsals, but she’s looking even more fit!

The 44-date runs for four months and covers the U.S., Canada and London, with plans to expand to the rest of Europe.

This time last year Britney was in turmoil and had to be stretchered out of her LA home but newly pictured in a revealing bikini top, it looks as though the starlet has finally got her groove back.

According to one fitness trainer, Spears has shed 20 pounds by doing two-hour cardio-and-strength-training workouts three times a week
