The two superstars have been hard at work in rehearsals for Saturday's (02.03.24) awards, which will take place at London's O2 and fans are in for a treat.
A source told The Sun newspaper's Bizarre column: "Kylie and Dua are going to raise the roof of the O2. Dua is opening the show with a bang and will have more than 30 dancers with her. She's also got a special surprise lined up to make it a real spectacle.
"It's powerful, punchy pop and will get everyone up on their feet for sure.
"Kylie's set is just as amazing and the O2 is going to become one massive party when she's on stage. Like Dua, Kylie's got an army of dancers who will be performing alongside her. She will be working through a medley of some of her greatest hits. It's going to look amazing, whether you're in the audience or watching at home."
Meanwhile, Green Day are said to be flying in from America for the show, with actors Joe Keery, Jonathan Bailey and Luke Evans all set to present awards.
Along with Kylie and Dua, performers will include Rema, Tate McRae, Chase & Status, Calvin Harris and Ellie Goulding.
A show insider added: "It is going to be really fast-paced as there are so many awards and performances to get through.
"The organisers wanted to pack in as much fun as possible and get the Brits back to being totally about the music.
"It is one of the biggest productions they've ever put on."
