Evans, who presented TFI Friday and Don't Forget Your Toothbrush on Channel 4 during the 90s, will join Christine Bleakley on the BBC One programme.
Evans said he was "honoured" to be involved in what he called a "much loved institution".

Last year, Evans made his TV comeback appearing as a guest on The One Show.
"I think what Adrian and Christine have done with the show is fantastic," said Evans.
"It has become a much loved institution in a relatively short space of time and I am honoured to be able to be joining the team. For me, Fridays have always been a little bit special and I want to do my bit to welcome people to the weekend."
BBC One controller Jay Hunt said: "The One Show is without doubt one of our most popular programmes and I am thrilled that Chris will be joining such a successful team.
"His unique presenting style and infectious enthusiasm will be a great addition to the show."
