Olly Murs has shot straight to the top of the singles chart with his debut single - and the X Factor runner-up says he's "over the moon".
The former call centre worker's song Please Don't Let Me Go has been much anticipated by fans who have waited for the release since he came second in the popular talent show last year.
The 26-year-old said: "I'm absolutely over the moon that my debut single has reached No 1. Especially since I was up against such stiff competition. Thank you so much to all my fans and everyone who bought the single."
The 2009 X Factor winner Joe McElderry did not enjoy immediate number one success with his debut song - he was beaten to the top spot by rap metal act Rage Against The Machine.
Their 1992 hit Killing In The Name was crowned Christmas number one after a internet campaign to keep another of Simon Cowell's acts off the festive top spot.
However, Joe's single The Climb did reach the top of the charts for the New Year number one a week later.
Taio Cruz's single Dynamite, which was number one last week, dropped to third position as Katy Perry scooped second place with her new single Teenage Dream.
Eminem's hit Love the Way You Lie, featuring Rihanna, was in fourth spot while Flo Rida's Club Can't Handle Me came in fifth.
Katy won't be too disappointed for missing out on the top spot because her new album, which has the same title, reached No 1 in the album charts.
Eminem's record Recovery, which was the number one album last week, dropped to second position.
