Olly Murs is the latest X Factor success story after scoring a number one with his debut single, Please Don't Let Me Go.
The 26-year-old from Essex, who was runner-up in the ITV show last year, knocked Taio Cruz off top spot in the UK charts.
The singer promised to pose naked if his single got the coveted position and now thousands of fans are hoping to see him get his kit off.
Olly told a magazine in August: "If my single gets to number one, I'll pose naked. I am telling you. I'm being serious. If I get to number one, I will do a naked shoot for Heat."
US pop singer Katy Perry narrowly missed out on top spot with her track Teenage Dreams.
