The Masked Singer is the British version of the madcap American singing competition where celebrities are disguised in elaborate costumes.
A panel of four celebrities - Ken Jeong, Davina McCall, Rita Ora and Jonathan Ross - try and guess the celeb from their singing and a series of clues.
But who is the American judge Ken Jeong? Many of you will recognise him from his fame-finding role as drug lord Leslie Chow in The Hangover series of films.
Who is Ken Jeong?
Fifty-year-old actor and stand-up Ken Jeong is from the US city of Detroit and is a qualified doctor, but he no longer practices after giving it up for a career in showbiz.
Throughout the 2000s he appeared in various TV comedies like The Office, Two and a Half Men, Curb Your Enthusiasm, as well as big screen comedies like Knocked Up, Role Models, Step Brothers and Couples Retreat.
But it was in 2009 that Ken's career took an upward trajectory when he starred as the gangster Mr Chow in The Hangover and as Ben Chang in the hit comedy Community.
He has fronted his own sitcom, Dr Ken, and cameoed in Avengers: Endgame in the scene where Scott Lang aka Ant-Man reappears after the snap which kills half of all living things in the universe.
Since then he's provided voices for films like Despicable Me 2, Penguins of Madagascar, Wonder Park and TV shows like American Dad and Bojack Horseman. In recent years he's guest judged on America's Got Talent and presented The Ellen DeGeneres Show.
He first starred on the panel for The Masked Singer when it started on Fox in the US in January 2019.
As well as appearing on the UK version, Jeong is due to be seen in feature films El Tonto and Boss Level in 2020.
The Masked Singer in on ITV on Saturday and Sunday.
