It made history as Ant and Dec revealed Lenny Rush was their youngest-ever Star Guest Announcer.

They then revealed their plans to ‘take over ITV’ for the final ever episode of Saturday Night Takeaway.

Speaking on the show, Dec said: “Next week is your last episode of your Saturday Night Takeaway.

“But the good news is it’s a live two-hour extravaganza, basically it’s going to be the mother of all parties.

“We’re taking over the whole of television centre.”

Ant then continued: “It’s going to be absolutely epic, we’ve got a super singalong live with Tony Hadley, we’ve got 7 Club, Kaiser Chiefs.”

They also confirmed Ant Vs Dec will be back with Stephen Mulhern for one final outing before Girls Aloud make an appearance.

The Sun was first to reveal how Cheryl Cole, Kimberley Walsh, Nicola Roberts and Nadine Coyle would make an appearance.

The Love Machine hitmakers will appear on the live finale on April 13 as Star Guest Announcers.

It comes as they are preparing for the start of their reunion tour in May, — the band’s first since 2013.
