The single taken from her album Teenage Dream tops the U.S. charts, pushing aside last week's winner Pink's 'Raise Your Glass'.
Katy Perry has exploded into the number one spot on the U.S. charts with "Firework". The singer's third chart-topping single from her latest album "Teenage Dream".
The singer rocketed up one spot to knock last week's Billboard Hot 100 champion Pink's "Raise Your Glass" from pole position. Rihanna has another new song in the top three - her "What's My Name" track with Drake is third - while the Black Eyed Peas' "The Time (Dirty Bit)" is at four.
Bruno Mars' latest soulful offering, "Grenade", rounds out the top five.
"Firework" is the third single from Katy Perry's 2010 summer album "Teenage Dream", which was released on August 24. In support of the album, she is going on a California Dreams tour next year.
