The 49-year-old stand-up comedian said that The Mighty Boosh star, 44, had “kept it quiet” about taking over from her on The Great British Bake Off even though the pair were working together on a project around the same time.
Nevertheless, she said that she “loved” the fact that her friend was now part of the show following its move to Channel 4.
Appearing on Lorraine today, she said: “I’m extremely fond of Noel, he’s absolutely terrific and I love the idea of him being in the Bake Off tent. It just makes me laugh.
“It’ll be very good to see how he deals with a croquembouche, do you know what I mean? In all ways. How he describes it, how he just embraces the whole thing. He’s great.”
She went on to reveal that she’d given him some advice about taking on the role and indulging in the delicious bakes, joking: “I said to him, ‘Two words Noel, elasticated trousers.’”
Mel also seemed to suggest that she missed the programme, which she departed from last year.
She explained to host Lorraine Kelly: “I’m thinking of them [the bakers], wondering what’s going on. Who the bakers are, all that kind of stuff. It’ll be something different.”
Mel left the show along with co-host Sue Perkins and judge Mary Berry last year after it was announced that Channel 4 had acquired the rights for the series from the BBC after a fierce bidding war between the two broadcasters.
The Great British Bake Off is set to return to Channel 4 later this year with Paul Hollywood and new judge Prue Leith, who is a veteran restauranteur and cooking writer.
When asked whether Mel would be teaming up with her comedy partner Sue, 47, again, she said that there was nothing on the cards at the moment but it could happen in the future.
“We have these endless plans and chats. We were singing songs from the Eighties until very late last night. Something will occur in some shape or form,” she said.
Lorraine airs weekdays on ITV at 8.30am.
