Alison Hammond was forced to apologise to viewers during Monday's This Morning after Dermot O'Leary turned the air blue.
Around half an hour into the ITV show, Alison had a " Big Brother " reunion with former housemate Kate Lawler as she presented the show's latest competition.
Dermot, 49, then surprised Alison and said: "Let's have a quick look at you and Kate in this iconic moment in the Big Brother house."
