Eight fresh young stars arrive at the music mansion to compete for an amazing prize - the chance to perform at Radio 1's Big Weekend. But they aren't the only new faces arriving in the mansion. On her own personal journey is new presenter Anna Maynard, and working with the singers is a new musical director, Max Cooke. This time the kids face a tricky vlogging challenge with online superstar Sophia Grace, and the mums make a big splash when they go head to head with footballing freestylers F2! But the big question is who will walk away with the win in the very first sing-off.

The eight kids head to London's West End to sing on the Aladdin stage. Their performance will be judged by Jasmine, played by Jade Ewen, and renowned choreographer Ben Clare. The mums take on an adrenaline-pumping zip-line in their next challenge, Drop the Beat, to try to secure their kid the final place in the sing-off.

Bars and Melody arrive in the music mansion to host an epic rap battle between the singers. Music maestro Max is in for a nasty surprise when the group take on his favourite Dua Lipa track. And things get personal in the mums challenge when they try to make a clay sculpture of their own child's head. Which mum will be artistic enough to win their kid the final Sing-Off spot?
