The singer's latest single currently holds the No. 2 spot on Billboard's Hot 100.

Perry closed out the Sunday night awards show with the recently released track off of her upcoming Prism album, sung from the Brooklyn Bridge.

Before the actual performance, the songstress was shown covered in a red, silk Boxer's robe with the word "Lioness" emblazoned on the back, fighting her way to the Brooklyn Bridge. 

Girls actress -- and personal friend -- Allison Williams introduced the the live rendition of the pop song. Once on the boxing-ring inspired stage, Perry was seen wearing a tiger-striped sports bra with metallic gold boxing shoes and bedazzled gloves, all of which thematically corresponded to the song's message of personal empowerment.

The performance also saw the "Last Friday Night" singer jumping rope, showing off some Muhammad Ali-inspired dance moves and then triumphantly brandishing a championship Boxer's belt, while flanked by two bikini-clad ring girls, holding sings that read "Game Over."

In the second week of it's release, "Roar" rocketed from No. 85 to No. 2 on Billboard's Hot 100, only second to the Robin Thicke's song of the summer, "Blurred Lines."

During the VMAs, fans had the opportunity to vote for which Perry single would be released before the Prism album drops on Aug 22. At the end of the show, it was announced that the song "Dark Horse" was the big winner. 

From a controversial performance by Cyrus to an unforgettable 'N Sync reunion, Perry gave one "last punch" to end the 2013 MTV VMAs in Brooklyn's Barclays Center.
