Alison Hammond left her This Morning co-host Dermot O'Leary blushing on Friday's show as they spoke about Tinder.
As the ITV daytime show returned from an advert break, Alison told father-of-one Dermot: "You do realise you can come a little closer to me now?"
As Dermot cosied up to Alison, she quickly commented: "Awwwww look how tall I am to you."
But Dermot was having none of it and fired back: "That's not fair! This thing, is that real?" he added, referring to Alison's hair which was tied up in a chic bun.
Ad Dermot tried to convince Alison that he's actually the same heigh as her, she teased him: "You're one of those guys who on Tinder says, 'I'm five foot nine', sure you're about five foot six!"
Referring to the popular dating app, Dermot then asked her: "Which way is the good way?" as Alison responded: "I'm swiping left for you because you're married!"
"No, I meant in a different world!" Dermot laughed, as Alison quickly added: "If you wasn't married, I'd swipe right! Oh absolutely!"
The mother-of-one then cheekily added: "You know what, we're all the same height horizontally aren't we? Do you know what I mean?"
Dermot looked a little bit taken aback as he said: "I read it in the book! I'm having a lovely time!"
