David Tennant will be hosting this year's Red Nose Day alongside Davina McCall on 13 March."It's going to be fantastic. There has always been a sense that Comic Relief is about everyone being able to join in," said the Doctor Who actor. "We can all help to make sure as much cash goes to all the people who need it most." Other highlights of this year's show will include Duncan Bannatyne and Peter Jones of Dragons' Den partnering on a Strictly Come Dancing Special and the stars of Gavin And Stacey releasing the comedy single Barry Islands In The Stream.
