Madonna injures ankle

Madonna's upcoming world tour has been thrown into jeopardy - the star has injured her ankle just two weeks before the live shows kick off.

The 'Material Girl' is currently in New York rehearsing for her Sticky & Sweet tour which will begin in Cardiff, Wales on August 23.

And she was photographed this weekend nursing a heavily bandaged foot - prompting fears that the 49-year-old may not be fully fit for the first date of the tour.

The mammoth trek will cover Europe and North America and will wrap up in Mexico City on 30 November.
