The 'Ready For The Weekend' singer, who has replaced Duran Duran as a headline act at the 2011 Virgin Media V Festival, claimed that he's "good" at producing music.
He told Radio 1: "It's been too much. I'm a producer, I make the songs, I can't stress that enough. I'm the guy that writes them, makes them and mixes them.
"No-one really does that, but that's what I'm good at it."
However, the 27-year-old insisted that he's looking forward to performing at the V Festival.
He said: "I can't wait to perform at V Festival - the crowds are always amazing in both Chelmsford and Stafford. It's going to be a lot of fun."
This year's Virgin Media V Festival takes place on August 20 and August 21 at Hylands Park, Essex, and Weston Park, Staffordshire.
