Holly Willoughby on Alan Carr: Chatty Man

It was an awkward day at work for the 'This Morning' presenter when she was forced to stare at a body double's private parts because her co-host was making ITV's Text Santa charity advert.

Speaking on 'Alan Carr: Chatty Man' - which airs tonight (04.12.15) at 10pm on Channel 4 - she shared: "Well can I just say if that was Phil's bum do you think him and I could have a working relationship with that view I have? That was a weird day because even thought that wasn't Phil, there was still a stunt bum, with a stunt man who I had to stand in front of and do the whole thing with. So I am still looking at a man's penis that I've never met before. Seriously."

To ease the situation Holly was forced to make small talk with the model, whose plan to impress the blonde beauty with his private parts backfired when he began to sweat.

She continues: "He was a very lovely chap and he had been waiting for a long time and by the time we were ready he had a sweat on. He pulled his jumper down over it so I couldn't really see anything. He had a real bead on, like the sweats. I was a bit worried about him and he seemed really nervous and I was talking to him to make it not so awkward. Then I was told, I don't know if this is true, but this is what I was told, that he had a bead on because he tied an elastic band around his bits and bobs to make it look bigger. I didn't even know that was a thing!"
