Cotton and Carr rejoin Sport Relief
Presenter Fearne Cotton whips comic Jimmy Carr into shape as they prepare for this year's Sport Relief.
The Radio 1 star sits atop the mouthy comedian brandishing a riding crop as the fundraising spectacular is launched today with an array of stars breaking into a sweat for charity.
Olly Murs, Lorraine Kelly, Kara Tointon and James Cracknell will be among those taking part in sponsored running events across the UK on March 25.
David Walliams has already raised more than £1 million for this year's appeal thanks to his 140-mile swim along the River Thames last year.
And Blue Peter presenter Helen Skelton is currently on course to raise a fortune through her 500-mile trek to the South Pole - skiing, cycling and kite-skiing for up to 14 hours a day.
In another challenge, celebrity teams representing England, Scotland, Wales and Ireland will compete to finish a 1,000-mile race - First Nation Home.
Stars such as Gethin Jones, gardener Diarmuid Gavin, Gemma Atkinson and rugby player turned Celebrity Big Brother contestant Gareth Thomas will feature in the teams heading around the UK and Ireland.
Fearne may have been getting some retribution after their gruelling cycle challenge in 2010, for which Jimmy turned up for only a brief stint in the saddle. She said: "I'm a huge fan of Sport Relief and thoroughly enjoyed whipping Jimmy Carr into shape for this year's campaign.
"Especially having spent five days of the last Sport Relief in a team cycling non-stop from John O'Groats to Lands End and Jimmy just popped along for one day - sweet revenge."
Cash from the Sport Relief weekend - from March 23 to 25 - will go towards vulnerable people across the UK and some of the world's poorest countries.
