Solo star Nathan Sykes has revealed that the most difficult song to write for his new album, 'Unfinished Business' was 'Famous' because he didn't want it to be obvious who it was about. 

During a Twitter Q&A last night, the musician and singer explained that he had to work out a way to disguise the subject matter so that people wouldn't be able guess who he was writing about: "Had to make sure it wasn't blatantly about the person who inspired it and didn't want people to think it was just about being famous."

When asked by a follower how he managed to "pull through all the obstacles faced" throughout his career so far, the "Over and Over Again" sensation said: "Nothing is ever easy but if you want something enough you will find yourself feeling like the biggest challenges are easy."
