LONDON: Troubled pop star Britney Spears is back in shape and her outfits are getting skimpier and skimpier. The singer, who is rehearsing for The Circus world tour, gave fans a glimpse of her new figure by posting her bikini-clad shots. In the pictures, Spears is seen working with choreographer Jaquel Knight, the man behind Beyonce Knowles’ moves in her Single Ladies video, and her body looks in great shape, reports thesun.co.uk.

It is difficult to think it was just a year ago that Spears was stretchered out of her home for a psychiatric evaluation. Her tour will feature three spectacular acts, from her messy meltdown to her recovery. It kicks off in her home state of Louisiana on March 3 and runs for four months, covers the rest of the US, Canada and London, with plans to expand to the rest of Europe. Spears will perform six gigs in London’s O2 arena in June.
