Britain's Got Talent 2016: David Walliams hits his Golden Buzzer for Ian and Anne Marshall

Even Simon Cowell is a fan of the singing lovebirds

Ian and Anne Marshall on Britain's Got Talent

David Walliams has given another outlandish act his Golden Buzzer on Britain's Got Talent 2016 - though singers Ian and Anne Marshall have also won the approval of Simon Cowell.

Ian, 64, and Anne, 61, took to the Britain's Got Talent stage in the run-up to their 44th wedding anniversary - and it is clear they are still as smitten with each other as they were four decades ago.

"Ian and I met back in 1972," they explained. "Ian was a chef in the army and I was in the Womens Royal Army Corps. We met on the Wednesday and we were married the next Saturday.

"People said it’d never last, but we’re 44 years down the road, and it’ll last to the end of our lives."

Although the pair were eager to share their undying love for each other with the world, they're also serious about the talent contest.

"We’ve come to Britain’s Got Talent to win it, obviously," they said. "The song we’re singing today is about us, and how we feel about each other even after 44 years of marriage."

There were some rather bemused-looking faces in the room when Ian and Anne begun their performance - belting out the Great Gatsby version of Beyoncé hit 'Crazy In Love'.

But they soon had the audience on side - with Amanda Holden and Alesha Dixon getting up to dance along, while David Walliams went to shake his booty next to Simon Cowell.

The crowd gave the couple a standing ovation, and David stood up on the judges' desk to bow to them - before walking over and hitting the Golden Buzzer with his foot.

"I think you really are the spirit of Britain’s Got Talent, the pair of you," the funnyman proclaimed. "You spend your whole lives doing something else, you have this beautiful relationship… and you picked a Beyoncé song for no apparent reason!"

And while David's previous Golden Buzzer acts Christian Spridon and Lorraine Bowen failed to impress Simon, the media mogul did admit to being fond of Ian and Anne.

"I just knew David was gonna do that," he smirked. "But actually, for once, I get it. It’s acts like you that make me love this show and love this country."

The result means that Ian and Anne are now the third act of the series to be guaranteed a place in the live shows, with Simon and host Ant and Dec's picks yet to be revealed.

Last week, Alesha Dixon gave her Golden Buzzer place to 100 Voices of Gospel, while Amanda Holden previously backed Beau Dermott.
