It’s taken them 19 years, but Ant and Dec have scored their very first UK number one single with Let’s Get Ready to Rhumble.

It was only meant to be a spoof when Ant and Dec transformed themselves into their 90s alter egos to perform the pop track UTV’s Saturday Night Takeaway last week.

But it seems plenty of people enjoyed their nostalgic trip down music’s memory lane and the comedy duo has rocketed to the top of the charts in the UK this week.

The 1994 single sold 84,000 copies this week, which is 64% of its previous total. It originally peaked at number nine.

A delighted and surprised Ant & Dec have announced they are donating their takings from the single to the Childline charity group.

Ant McPartlin said: "Wow. This week has been crazy! We never expected such an amazing reaction to us performing the song on the show. To be number one in the Official Charts is just unbelievable!"

Declan Donnelly added: "To get a number one single with this song 19 years later is very surreal, but we're genuinely chuffed!

"Thank you to everyone that has bought the single, as you are helping Childline, a charity that we are very passionate about."

Kodaline’s High Hopes currently holds the top spot in Ireland, with Pink, Bastille, Passenger and Justin Timberlake following respectively.
