Jessie J has regained her position at number 1 in the UK singles chart tonight (February 12) with 'Price Tag' after being pushed into second place during the midweek update. 

The Essex-born singer is back at the top spot after losing her place on Wednesday to Chipmunk's new single, which features Chris Brown, called 'Champion'. However, tonight Chipmunk is celebrating a number 2 hit with his new track. 

Lady Gaga's long awaited new release, 'Born This Way', entered the chart this evening at number 3, Bruno Mars slides into fourth place with 'Grenade', and Adele completes the top 5 with her single 'Rolling In The Deep'.
