Ed Sheeran has joked that he owes Pharrell Williams a hat for producing his hit single Sing which has scored him his first UK number one.

Taken from Sheeran's latest album X, the song is currently number three in the Irish singles chart and is also winning him new fans in the US.

Speaking to MTV Sheeran said, "I swear Pharrell has special foresight. I said I wanted to release Don't as the first single. He said it should be Sing and it would do over 100,000 in the US and sure enough, it's doing 140,000. I owe him a hat or something."
