He wrote in a post: “Honoured to be hosting The Big Night In with #SirLennyHenry @mcguinness.paddy @zoetheball @davinamccall.
“This is the first time Children In Need and Comic Relief have partnered – in these times of togetherness we’re there for those who need us most.
“Join us Thursday 23rd April from 7pm BBC1 for what ever happens!! Huge thanks already to those who’ve offered help. See you then.”
Matt will front the show alongside Sir Lenny Henry, Paddy McGuinness, Davina McCall and Zoe Ball, with Peter Kay also in the mix.
