James Bay has been one of this year's biggest successes in music, but it doesn't seem like there's any rivalry between him and Ed Sheeran.
In fact, Sheeran even joined the singer on stage the other night at the Cambridge Corn Exchange, duetting on Bay's song 'Let It Go'.
Apparently, the pair met and became friends at the BRIT Awards earlier this year, when Bay won the Critics' Choice Award.
"Ed doesn't have to turn up and guest on mates' records or gigs, but he's a real musician who just really loves to play," he later said. "What's awesome for the rest of us is that he's so generous with that."
Watch them duet on the song below:
