This Morning viewers have been left gobsmacked after learning Dermot O’Leary ’s real name. The former X Factor host, 51, made the shocking admission on Monday’s edition of the ITV programme, even surprising his co-host Cat Deeley.

On Tuesday's episode of This Morning, Dermot O'Leary revealed his real name—and it isn't Dermot. As the programme kicked off, Cat Deeley asked whether or not her ITV co-star had a middle name. He said: "My first name is Sean, Sean Dermot O'Leary." After a brief silence, taken aback, she replied: "Your first name is Sean? How did I not know that?"

ITV This Morning presenters Cat Deeley and Dermot O'Leary shared some exciting baby news during Tuesday's programme as they congratulated a colleague on the arrival of their son.
