About the show
Ant & Seb, a Welsh duo from The X Factor, wowed audiences with their viral audition of “Mysterious Girl.” Ant’s smooth vocals, combined with Seb’s Jamaican-inspired robotic rap and comedic flair, created one of the show’s most iconic moments. Although the judges criticized Seb, audiences loved the performance, sparking memes like “When your mum says take your brother with you” and widespread UK media attention.
They’ll be performing their crowd-favourite “Mysterious Girl,” along with feel-good hits and their viral Christmas charity single Sprinkle It, released in aid of Shelter Homeless Charity. The track reached No.1 on the Amazon Music Hot New Releases chart, ahead of major artists including Drake and Post Malone.
Despite not advancing on the show as a Novelty Act, the duo has taken social media by storm - a TikTok clip announcing their return hit 480,000 views in 24 hours, with fans calling it “the best day of my life.”
