The 41-year-old British actor - who moved to Los Angeles in 2015 to take over hosting the US chat show - opened up about relying on body control underwear after his guests The Marvelous Mrs. Maisel star Rachel Brosnahan and drag queen RuPaul discussed their uncomfortable costumes.
Corden said: “I think I'm making a sacrifice wearing these Spanx. I'm not even joking. My New Year's resolution is to try to get to a point where I do one show this year, not wearing Spanx.”
The Cats star added: “It'll be like I'm free, Ru, I won't know what to do! I'll be breathing.
“Oh you'll know babe. You'll know. I'll shout it from the rooftops. It'll be my first ever Instagram story!”
Corden’s breakthrough acting role was in Kay Mellor’s ITV drama Fat Friends, about members of a slimming club, which ran for four series between 2000 and 2005. Corden met Gavin and Stacey co-creator Ruth Jones on the show and they came up with the idea for the sitcom about the coming together of two families from Wales and Essex.
Corden opened up about battles with his weight last year when he spoke out about fat shaming.
Responding to a joke by talk show host Bill Maher, Corden said: “Fat shaming never went anywhere. Ask literally any fat person. We are reminded of it all the time.”
“There’s a common and insulting misconception that fat people are stupid and lazy, and we’re not… We know that being overweight isn’t good for us and I’ve struggled my entire life trying to manage my weight and I suck at it. I’ve had good days and bad months.”
