Justin Bieber and Nicole Scherzinger are on hand to provide a bit of light entertainment in the final heat of this charity dance contest. Our own Keith Duffy is slipping on his dancing shoes tonight to try and raise a bit of dosh for Comic Relief. He'll be going up against Vanessa Feltz, ventriloquist Nina Conti, newsreaders Ore Oduba and Sonali Shah, and comedian Lee Nelson to try and secure a place in the final alongside Tim Vine, The Soap Stars, Antony Cotton and Katherine Ryan. If he cracks out those Late Late Show moves we're sure he'll be just fine!
