Listen to Katy Perry on iHeartRadio

Katy Perry has been announced as the latest performer for this month's MTV Video Music Awards.  The four-time VMA winner is set to perform her new single "Roar" at the August 25th awards show at Brooklyn's Barclays Center. 

The single is the first from Katy's forthcoming third studio album Prism.  The VMA performance will mark her third time taking the VMA stage.  She performed her debut hit "I Kissed A Girl" in 2008, and came back the next year to do a cover of Queen's "We Will Rock You" with Aerosmith's Joe Perry. 

"Roar" became available for download on iTunes on Monday after leaking online over the weekend. Listen below:
