She joked: "Do you know what? I'm gutted I'm not presenting GMB when you're on Lorraine because there is so much we could say, isn't there when you take the hot seat?
"Don't worry I'll just text you all of the humiliating insults I would have normally said on air."

"Adil and Ranvir, this is the kind of morning you would love, just cruising along the Thames. Let's go!"
But as he tried to walk along the boat, he fell before bursting out into laughter.
Ranvir, who was back in the studio, joked: "You haven't quite found your sea legs!
"Can I just say what an honour it is to the be on the show with such a professional"
