BBC Radio 1 DJ Nick Grimshaw will team up with the likes of Jessie J and Little Mix for a series of daring Comic Relief challenges.

The Breakfast Show host is doing his bit this year for Red Nose Day, which is due to take place on Friday (March 15).

Grimshaw has revealed that a quartet of famous faces will be joining him for some "crazy" tasks - with one including maggots. He said:

"Guests popping in are David Walliams, Jessie J, Little Mix and Conor Maynard and there will be some crazy challenges – one involves me, a bath and maggots."

Jessie J meanwhile is already doing her bit for this year's Comic Relief, agreeing to shave off her hair on live TV.
