Ricky Hatton, the former world welterweight boxing champion who finally retired from the sport after losing a comeback bout in November, will compete in this year's Let's Dance for Comic Relief.
The boxer will be joined on the charity celebrity dancing show by three comedians: Nina Conti, Tim Vine and Jon Culshaw. Further participants are to be announced ahead of the start of the series on 16 February on BBC1.
Alex Jones and Steve Jones return to host the series, with judges including Frank Skinner and Jo Brand.
“I'm ridiculously excited to be back on Let's Dance," said Alex Jones. "Earlier this year Steve and I went out to Malawi to visit a number of projects funded by Comic Relief, and we can't wait to get stuck in, knowing that the money raised this Red Nose Day will go towards helping families in Africa and in the UK that desperately need it."
Steve Jones added: "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!"
Previous winners of the series include Rowland Rivron, Robert Webb and Rufus Hound.
The Let's Dance grand final will air on 9 March. Red Nose Day, Comic Relief's main fundraising event, is on 15 March.
