Undercover on American Idol

The Undercover skits have tricked some of the biggest names in showbusiness and Ant’s favourite is when they fooled their Britain’s Got Talent boss Simon Cowell in 2014.

The pair donned bandanas, sunglasses and badly-groomed beards and had a go at auditioning for American Idol where Cowell was on the judging panel.

The pair pretended to be brothers and performed Paula Abdul’s Opposites Attract to an extremely confused panel.

Talking of his favourite moments, Ant says: “Top one has got to be our Undercover on Simon Cowell. It was the first one we did. We flew to LA and auditioned for American Idol, which was really nerve-racking.

“Also the prosthetic make-up didn’t turn up, so we had to do dodgy beards and stick-on earrings – but it worked.”
