Jessie J is tonight celebrating her first UK number 1 single with 'Price Tag', which features B.o.B.

This is the Essex born singer-songwriter's second release and after scoring the midweek number 1 has managed to hold onto the top spot for the official announcement. She is also at number 7 in the singles chart this week with 'Do It Like A Dude'. 

She said to Radio 1's Reggie Yates:

"It's an honour to be a number 1 in the UK because I'm British, and I'm super-proud to be British so thank you!"
