Olly Murs worries that his fame will soon evaporate.

The 30-year-old star has enjoyed considerable success since appearing on the sixth series of 'The X Factor' in the UK in 2009, but he fears losing fans if he's not constantly releasing music.

The 'Heart Skips a Beat' hitmaker reflected: ''My fans are so loyal but I always worry they will jump ship. Loads of great artists have come back and are not selling records anymore. I know if I'm not at the top of my game there will be a new whippersnapper from X Factor to take my place.

''You have to be worried because it keeps you on top of your game.

''I couldn't take three years out and come back with an album. A few artists can do that now, Adele or Ed Sheeran, but I'm a different artist.

''I have to keep going and working hard for success. I understand how fickle the industry is.''

Much of Olly's success has been attributed to his likeable personality, and despite amassing a considerable fortune, he admits he still loves a bargain.

He told the Daily Star Sunday newspaper: ''I love a bargain, who doesn't? If I can get a 'buy one get one free', then of course I'm going to buy it.''
