James Corden sang with Coldplay on Sunday (21.08.16).

The 'Late Late Show' host was ''a little nervous'' to join the British group on stage in Los Angeles to sing 'Nothing Compares 2 U' in tribute to late singer Prince, but won over the Rose Bowl audience with his vocals.

According to E! News, James - who had been introduced by frontman Chris Martin as a former member of the band - kicked off the song before the group joined in to sing with him.

And after the track had finished, the singer produced a cake and had the audience sing 'Happy Birthday' to the special guest, who turned 38 on Monday (22.08.16).

Chris was previously a guest on James' 'Carpool Karaoke' segment and the talk show host recently recalled about how much the 'Up & Up' hitmaker enjoyed belting out his own hits in his car.

He said: ''After every song he was like, 'Oh, I haven't heard that for ages!' Or, 'It brings me back to where I wrote this!.

''It's actually quite a lovely thing for them to reminisce; they hear their whole career in eight songs.''

James thinks the segment shows a very different side to his guests.

He said: ''There's an ease and an intimacy to it where you'd never ever see stars quite so unguarded.

''l'm different from when I'm doing the show when there's an audience of 200. Seeing a huge megastar sing their hits in the same environment that you and I sing on our way to work -- it's humanising.''

And the popular presenter feels ''lucky'' to be treated to such intimate performances from huge stars when he films the show.

He said: ''To sing 'Tiny Dancer' with Elton John in a car, you just think: If this was an auction prize, it would go for hundreds of thousands of dollars. I feel lucky every time I get in the car with any of these people who I just really admire and respect.''
