Ant and Dec have revealed that they are still pinching themselves over their chart-topping success with revived hit, Let's Get Ready To Rhumble.
The TV duo - Anthony McPartlin and Declan Donnelly - are celebrating their first number one single 17 years after their chart career came to an end, after the 1994 song knocked The Saturdays off the top spot.
"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," Ant told Officialcharts.com.
Dec added: "To get a number one single with this song 19 years later is very surreal, but we're genuinely chuffed."
The pair, who also tweeted their thanks to fans, plan to donate the profits of the single to Childline.
Download sales for Let's Get Ready To Rhumble soared after the duo reprised their PJ and Duncan alter-egos and performed the song on their Saturday Night Takeaway show alongside Big Reunion stars Blue, 5ive and Atomic Kitten on March 23 as a joke.
"We thought, well, we could possibly dust off the old baseball caps, and give it a go, for a laugh," Ant told ITV's Daybreak.
"The production team on Saturday Night Takeaway went mad, 'Oh yeah, we remember that song. Let's do it'."
Dec added: "We did a little bit of rehearsal on Thursday. We had four hours in our schedule, to rehearse the dance. We spent an hour and it all came back to us. We've obviously done it so many times in the past."
