Britain's Got Talent presenters Ant and Dec shared a hilarious tribute to the ITV talent show judges on their 10 year anniversary together.

The popular presenters opened Saturday's episode of Britain's Got Talent by surprising the judging panel - Simon Cowell, Amanda Holden, David Walliams and Alesha Dixon. 

The beloved duo surprised the judges with Union flag bunting as well as themed red, white and blue balloons alongside a shiny blue number ten balloon.

Before unveiling the surprise, Dec said: "This is the 10th series that you guys have been together as a panel. We got you a gift."

Alesha Dixon immediately jumped in to say: "Don't you'll make me cry!"

The ITV presenters then unveiled a barbershop quartet from behind a silver curtain to serenade the panel. 

The quartet sang these hilarious lyrics: "Congratulations on your 10 year anniversary, we all thought it would end up a wreck but from the start who's been there to guide you?

"The nation's favourite duo Ant and Dec!"

David Walliams was quick to spot that the supposed anniversary tribute seemed to mention the presenting pair a fair amount.

Walliams then teased: "Quite a lot about you in it, I'm just saying.

"It ended being about you as well," leading the presenters and the rest of the judges to burst into hysterics.
