A month at No. 1 for Bruno

Bruno Mars is celebrating a month at the top of the Big Top 40 chart with 'Grenade'.

It was one of the closet chart battles of the year with Bruno and Ke$ha swapping place through out the week but Bruno managed to stay on top keeping Ke$ha's 'We R Who We R' in second place.

This week's highest new entry went to Chris Brown, obviously Chris has been missing from the chart for a little while but he made his return with the brilliant 'Yeah 3x' which flew in to our chart at No. 7 on Sunday. 

This week it's all eyes of BRITs Critics' Choice winner, Jessie J.  Her second single 'Price Tag' which features B.o.B has been rushed out and is available to download now, so next Sunday we could have to songs from Jessie in our top 10.
