Singer Ed Sheeran has opened up about his mystery hand injury, revealing he sliced open his fingers on broken beer bottles.

The British star sparked fears for his health last month (Sep13) after posting photos of his bloodied and bandaged hands on Twitter.com and telling fans about a late-night trip to a hospital emergency room in Nashville, Tennessee.

Now Sheeran has admitted the cuts were the result of a bizarre accident - he hurt himself trying to play the drums with beer bottles at a late-night karaoke bar.

He tells Britain's The People newspaper, "I was playing with the bottles when I felt light-headed. I had blood pouring down me, it was on the floor and on my feet."
