Kendra Wilkinson heads Dancing with the Stars line-up

Kendra Wilkinson and Kirstie Alley are among the celebrities taking part in the 12th series of 'Dancing with the Stars'.

The former Playboy model and the 'Look Who's Talking' actress will battle it out on the dancefloor against the likes of former boxing champion Sugar Ray Leonard, NFL star Hines Ward and model Petra Nemcova.

Speaking about taking part in the show, Kirstie - whose weight has fluctuated over the years - said: "We're going to try to not fall on our butts the first week out. That's what I'm going for."

Other celebrities to take part include actor Ralph Macchio, singer-and-actor Romeo, talk show host Wendy Williams, radio personality Mike Catherwood and WWE star Chris Jericho.

Former Disney actress Chelsea Kane will also compete and admits the nerves are already starting to show.

She said: "I don't know how I'm going to react to the judges when there's a camera on my face and I'm trying to smile through it. Hopefully, I won't ruin my make-up."

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.
