Ant and Dec prank Simon Cowell not once but twice during this seasons launch show of Saturday Night Takeaway.
Having previously pranked Simon on their first show 20 years ago when they dressed up as contestants on American Idol, Simon fell for it again.
The first prank involved Simon riding his bike in Malibu. Ant said: 'It was even sweeter getting him the second time round because we also got him during his downtime as he’s riding his bike around Malibu, it’s very, very funny.'
Dec added: 'We are ending the Undercovers where we started… with Simon Cowell! Our first ever Undercover was on Simon in LA when he was a judge on American Idol.
'So we've gone back and got Simon Cowell again. We went out to LA and gave him the day from hell whilst he was judging on America's Got Talent.'
The second prank saw Simon in a metal box on America's Got Talent where he was told they had lost the key to release him.
