Britney Spears is being whipped into shape – literally – by dance mastermind Wade Robson in preparation for her forthcoming world tour.

The choreographer – who worked with Brit on her steamy Slave 4 U video and was implicated in her breakup with Justin Timberlake – reportedly has the recovering singer working out with a whip.

 He tells The Sun, “She reached out to me and said she wanted to get the old team back together.

“So we’ll go into rehearsals in January for a March start.”

And her gruelling efforts to get back in shape have clearly paid off.

The pop princess showed off her newly-svelte figure as she left a dance studio yesterday.
