James Corden shares hilarious story about when Stevie Wonder called to serenade his wife

It's one of Stevie Wonder's most iconic songs ... but when James Corden asked the music legend to call his wife to tell her he loves her, it didn't quite go to plan.

During his appearance on The Ellen DeGeneres Show yesterday, Corden revealed he got Wonder to call his wife Julia while filming 'Carpool Karaoke' to serenade her a few years ago.

But she happened to be in a very unromantic place when he sprung it on her.

"What I didn't know when I got home, is my wife was actually in a bathroom stall when the phone rang," Corden said while laughing.

"I had this gorgeous image of her being completely overwhelmed with emotion but she was literally in a toilet at a restaurant," he added.

It's the thought that counts!
