First Look: Ant & Dec prank Holly Willoughby on set of Surprise Surprise

Ant & Dec have released pictures of their undercover prank on Holly Willoughby in their latest Saturday Night Takeaway stunt.

Willoughby is shooting an episode of her show Surprise, Surprise when the Geordie duo trick her into believing she is reuniting charity worker Annabel with her boyfriend Richard (played by Ant).

Annabel is joined on stage by her fellow colleagues (played by actresses) and her boss Jean Luc (played by Dec).

Willoughby announces the surprise to Annabel – a performance live in the studio by her favourite band Blue. The boyband are joined by Richard, who intends to serenade Annabel and propose.

However, there is a sudden turn of events in the studio when Annabel rejects Richard. When the stunt is revealed, Willoughby is shocked and says: “Oh my God. It’s you. I nearly threw up.”

“I had no idea, I never thought I would be fooled but I honestly didn’t twig. As far as I was aware we had a relatively simple surprise, a boyfriend proposing to his girlfriend, but it all went wrong,” said Holly after the prank.

“I felt my heart sink when she said no. You never think anyone would say no! I was relieved when I found out it was a stunt but the boys best beware, I like a prank so may just have something up my sleeve!”

The full sketch airs on this week’s Ant & Dec’s Saturday Night Takeaway, at 7pm on ITV.
