Veteran entertainer Donny Osmond is returning to the ballroom as a guest judge on Britain's Strictly Come Dancing competition.

The Puppy Love hitmaker won the U.S. version of the reality show, Dancing with the Stars, in 2009 and now he will use his experience to rate competitors across the Atlantic.

Osmond will join U.K. judges Len Goodman and Bruno Tonioli, who are both regular judges on Dancing With the Stars, Craig Revel Horwood and Darcey Bussell on the panel for one week only this autumn (14), and he has urged competitors to prove their worth on the dancefloor in order to win him over.

He says, "It's a huge honour to be asked to guest judge on Strictly Come Dancing. I know what it's like to hold that trophy in your hand, and believe me, it's worth all the blood, sweat and tears you put into your dances.

"I'm going to be a tough judge, and the contestants are really going to have to give me their all."

The 12th season of the U.K. series, which launched earlier this month (Sep14), features actress Jennifer Gibney, EastEnders actor Jake Wood and singers Pixie Lott, The Saturdays' Frankie Bridge and Blue star Simon Webbe among the competitors showing off their fancy footwork.
