Perry, 28, played her new single, "Roar," in front of a live audience, while prancing around inside a boxing ring and wearing nothing but a tiger print sports bra and boxing shorts.
This year's MTV Video Music Awards were held at Brooklyn's Barclays Center, but Perry opted to sing outside, in front of a gorgeous New York City backdrop.
Perry, a four-time VMA winner, released "Roar" on Aug. 10, and the song has been widely embraced by pop music fans across the globe.
The 28-year-old took to Twitter to reveal why she wore combat sports gear during her performance. She said it was a bit of a preview of the official video for the song.
"Hitting #VMA carpet! Can't wait to show u my 👀 of the 🐯! Want a sneak peek at the #ROARVIDEO? Have your @Shazam on during preshow or show!" Perry tweeted.
Perry was never known to be a fan of women's mixed martial arts or any other combat sports, so the performance shocked more than a handful of MMA supporters.
Whether you loved it or hated it, Perry did her part to get the word out about her new song and album. The airy outdoor Brooklyn setting gave Perry plenty of space to work with, and she certainly proved to be one of the more memorable performances of the night.
Perry may not be a budding WMMA star, but she took full advantage of the spotlight by jumping rope and shadowboxing like a world champ.
Not only was Perry definitely more entertaining than Lady Gaga’s opener, she also flew like a butterfly and stung like a bee. Props to Perry for packing one of the evening's true hard-hitting punches.
