Comedians and sports stars will be among those hitting the dancefloor for a new series of Let's Dance For Comic Relief.
Fifteen contestants will battle it out in weekly heats before the 2013 champion is crowned in the grand final.
Former boxing champion Ricky Hatton will be taking part, alongside impersonator John Culshaw, ventriloquist Nina Conti and stand-up comic Tim Vine.
They will be attempting to emulate the success of television presenter Rowland Rivron, who wowed audiences with his routine to Fatboy Slim's Weapon Of Choice last year.
Host Steve Jones said: "It's still the most fun I have on TV so I am ecstatic Let's Dance is back with a whole host of famous faces along with famous arms, legs, necks and fingers all attempting to dance for our viewing pleasure."
Co-host Alex Jones said she was "ridiculously excited" about the series, which raises money for the Comic Relief fund to help those in Africa and in the UK.
She added: "We have some of our best comedians as panellists, and an unbelievable line-up of brave celebrities who are all prepared to don their dancing shoes to raise lots of money for this year's Red Nose Day."
Judges for this year's Let's Dance, which starts on February 16 and ends on March 9, include Frank Skinner and Jo Brand. Viewers vote for their favourite performer each week, with the judges also choosing a runner-up to compete in the final.
