Watch James Corden Celebrate His Birthday By Singing A Prince Tribute With Coldplay

The band had a special surprise for him.

We're used to seeing Late Late Show host James Corden singing with today's hottest music artists behind the wheel of a car, but Sunday night, he and Coldplay collaborated the old-fashioned way — on stage in front of thousands of people.

James joined the band for their concert at the Rose Bowl in Los Angeles, where he helped them pay tribute to late icon Prince with a cover of "Nothing Compares 2 U." Frontman Chris Martin introduced James by jokingly calling him a former member of the band who chose to leave them.

The late-night host then explained how the appearance came about, saying, "So this was an idea that Chris said to me, he said, 'I think you should come and sing this at the Rose Bowl.' I'll be honest, I didn't know how big it was when I said yes."

James and the guys then went on to give a moving performance worthy of the huge venue. When it was over, the band had a special surprise up their sleeve. Monday happened to be James' birthday, so they brought him a cake while Chris serenaded him.

It's the least they could do considering how James continues to support musicians. New data shows that Carpool Karaoke gives the artists whose songs are featured a boost in popularity, as more people are inspired to stream their music and follow their social media. That's definitely cause for celebration.
