Discussing his latest road trip show with Phillip Schofield and Holly, the comedian revealed that one of his favourite games to play with his friends is stealing their phones and sending a friend an unsuspecting text.
The blonde beauty, 36, then stunned Jack by revealing that she had fallen victim to his game and had actually received a raunchy photo from the 28-year-old.
“You sent me a photograph… It obviously wasn’t from you,” teased Holly.
The presenter then teased that she still had the photo and set about locating it.
After explaining that he didn’t know what was coming, Jack was completely horrified when he was shown the saucy photo, which couldn’t be aired on daytime television.
Visibly gobsmacked, he exclaimed: “That’s not mine! I don’t own those boxer shorts.
“I’m so sorry national treasure, Holly Willoughby,” Jack continued.
As the trio finished giggling over the photo, they tried to compose themselves for the rest of the interview.
However, this didn’t last long as a goat from the previous yoga segment made it’s voice known from off-camera.
