KIDZ BOP will be the opening musical act for this year's 'Children In Need'.
The youngsters - whose seventh album 'KIDZ BOP 2021' is in the UK top 40 - will perform a medley of hits from the past four decades to celebrate 40 years of the BBC's charity telethon.
The group - comprised of 14-year-old stars Twinkle and Mia, 15-year-old Max and Ashton, and 11-year-old Mandy - will finish their set with one of their biggest current singles, with a "special Pudsey twist".
In three years since their launch in the UK, KIDZ BOP have sold more than 418,000 albums, and amassed over 200 million YouTube views on their channel with over 210 million audio streams.
They have also gathered a passionate fan base, including famous faces such as Victoria Beckham, Mel B, Stacey Solomon, Kevin Jonas, Mario Lopez and Sam Faiers.
Other performances on Friday night (13.11.20) will feature stars from 'Strictly Come Dancing', 'EastEnders' and 'Doctor Who'.
And the West End casts of 'Cinderella The Musical' and 'Six' are joining the fun, as well as singers Beverley Knight and Shawn Mendes.
For this year's telethon, former sports star Alex Scott will join as co-host alongside the returning Mel Giedroyc, comedian Chris Ramsey and actor Stephen Mangan.
Alex said: "It feels so surreal to be a presenter on 'BBC Children in Need' - it’s a complete honour. It has been a show which I have grown up with, so to be joining the presenting line-up is amazing.
"I don’t think a little eight-year-old Alex watching at home all those years ago would have ever dreamed that one day she could be presenting it. It goes to show that anything can happen, no matter your circumstances or background - never stop dreaming."
'Children in Need' airs on BBC One from 7pm on Friday 13th November. 'KIDZ BOP 2021' is available to buy now at all online retailers.
