[NEWS] Bruno Mars Ends Katy Perry's Reign

According to the Billboard's Hot 100 chart, Bruno Mars has managed to knock Katy Perry out of the top spot with his song "Grenade."

As many may know, Katy Perry has been sitting pretty for three consecutive weeks at number one with her single "Firework."

Bruno will have to watch out, however, as all of the singles Perry has released off of her Teenage Dream album have managed to top the charts. With news that she is set to make "E.T." her next single, Mars may not be number 1 for long.
