Ed Sheeran

For the last three years or so, English singer-songwriter Ed Sheeran has been conquering the hearts of teenage girls worldwide with his sugar-coated love songs, but he's also been hard at work writing material for superstars like One Direction and Taylor Swift. Expectations are tuned up to the max for his second album, x, produced by none other than Rick Rubin and Pharrell Williams, and scheduled for release in late June.
