Petra Nemcova is to take part in the 12th series of 'Dancing With The Stars'.

The stunning supermodel model - who once dated James Blunt - has joined the line-up of the US show and will battle it out on the dancefloor against the likes of Kendra Wilkinson, Kirstie Alley and former boxing champion Sugar Ray Leonard.

Newly-engaged Petra - whose first fiance British photographer Simon Atlee was tragically killed in the Indian Ocean tsunami tragedy in 2004 - will also compete against stars such as actor Ralph Macchio, singer-and-actor Romeo, talk show host Wendy Williams, radio personality Mike Catherwood, WWE star Chris Jericho and former Disney actress Chelsea Kane.

The celebrities - whose professional partners have not yet been announced - have just three weeks to prepare before the show kicks off on March 21.

Previous winners have included Jennifer Grey, Nicole Scherzinger and Donny Osmond and it is one of the most watched TV shows In America.
