Chart-topping girl band Little Mix are set to perform as part of a star-studded line-up at BBC Radio 1′s Teen Awards.

The group, who are celebrating scoring their fourth number one single with break-up anthem Shout Out To My Ex, will be joined by Jess Glynne, DNCE, The Vamps and Shawn Mendes for the seventh annual awards ceremony.

More than 9,000 14 to 17-year-olds are expected to attend the event, hosted by Radio 1 Breakfast Show host Nick Grimshaw, at the SSE Arena in Wembley, north London, on Sunday afternoon.

The awards recognise the selflessness and bravery of the UK’s young unsung heroes and also honour stars in the music, entertainment, online and sporting industries.

Last week, the Duke and Duchess of Cambridge welcomed the Teen Heroes of 2016 to Kensington Palace for a reception ahead of the ceremony.

The group, who were joined by Nick and fellow Radio 1 DJs Clara Amfo and Greg James, were praised by Prince William for being “shining lights” for their peers.
