ITV This Morning's Alison Hammond responds to Dermot O'Leary calling her a b***h live on air

This Morning viewers were left open-mouthed when they realised Dermot O'Leary called his co-host Alison Hammond a b***h live on air. The pair were reunited on the ITV daytime show on Monday (July 18) for their second week as full-time hosts before several familiar faces take over until Holly Willoughby and Phillip Schofield's return in September.

But Dermot and Alison didn't look set to last the week after former Big Brother contestant Kate Lawler presented the show's competition segment. Her appearance on the programme, albeit via video link, meant Alison had a 'Big Brother' reunion with her friend as they appeared on the reality show together in 2002.

Dermot, 49, then surprised Alison, 47, with a throwback clip of the pair during their time in the famous house. He said: "Let's have a quick look at you and Kate in this iconic moment in the Big Brother house." The footage also showed Dermot presenting the show's spin-off, Big Brother's Little Brother, which he hosted from 2001 until 2008.

After seeing the clip, Alison poked fun at her co-star, saying; "Look at you with a bald head, you should so go back to that bald head. Why don't you shave your head? Look how fit you look." The pair continued to joke with one another as Alison said: "You were so good on that show," and Dermot replied: "Just at that show?" to which Alison responded, "Yeah."

Laughing, Dermot then raised his glass of water and said "such a b***h," whilst seemingly forgetting he was on daytime TV. Seconds later Alison, who looked rather shocked, then responded "oops" as she quickly ushered "apologies for that." However, Dermot seemed unbothered and added: "Oh sorry,"
