Jonas Altberg (Basshunter) was the ninth star to enter the Celebrity Big Brother house tonight.

Swedish born Jonas is best known for his number one dance hit “Now You’re Gone”. Which was the most played song online in the UK in 2008.

Jonas was still living with his parents aged 24 where he first started messing around with computer music programmes on the internet in his bedroom. In April 2006 he signed his first contract with Extensive Music/Warner Music releasing his first single, “Boten Anna.” In Scandinavia the song became an instant hit and was the first ever Swedish language song to reach number one on numerous charts around the world.

At the end of 2007, Basshunter released a re-recording of “Boten Anna”, titled “Now You’re Gone”,. The song subsequently charted at number one on the UK Singles chart (knocking Coldplay off the top spot) and stayed there for 5 weeks. It was the biggest selling dance single of 2008. His album “Now You’re Gone: The Album” was released in July 2008 and went directly to No1 in the UK and sold gold and platinum in several countries around the world.

Jonas has just returned from DJing at a New Years Eve party for the President of Kazakhstan and does a mean impression of Arnold Schwarzenegger. He claims Big Brother is his favourite reality TV show and is excited about meeting the rest of the celebrity housemates.

Jonas promises to be an unpredictable housemate who just has to get off with someone in there! What do you think of Basshunter? Leave your comments below.
