Matt Barbet and Gaby Roslin will present the two-hour live show every Saturday from 9.30am to 11.30am.
It will include panel discussions with celebrity guests, as well as news round-ups and a weekly recap.
Roslin said: "It's going to be fun and Matt is a really nice guy. He's really very engaging and he has got a lovely twinkle in his eye and a lovely sense of humour."
Barbet added: "I remember watching Gaby doing The Big Breakfast, which was a huge show. She has got tonnes of experience and there is an awful lot she can teach me.
"I'm looking forward to sitting alongside her and hopefully making her laugh and enjoying what we're talking about but also learning a thing or two."
Roslin's recent TV experience includes guest-hosting Lorraine,
