Katy Perry Gonna Knock You Out With Her VMA Brass Knuckles

Check out the blingy ROAR microphone she'll use at Sunday night's show.

Roar if you're ready for the VMAs!

Katy Perry is on her way to the 2013 Video Music Awards, ready to close Sunday night's show after performers like Lady Gaga, Miley Cyrus and Robin Thicke have graced the stage. And of course, she has to do it in style.

The Prism singer revealed her blinged-out microphone for her VMA performance on Instagram Friday (August 23) night. It's all-gold — much like her giant metallic semi — and brass-knuckled, with bold, cherry-red letters spelling out "ROAR" on each ring. Here's to hoping Perry won't knock anyone out!

Bedazzled mics aren't new to Katy. Remember her shiny rainbow mic or her American flag jewels on her Obama rally mic?

Fans, who recently unlocked lyrics to two Katy songs, gushed over the prop, with one fan tweeting, "I dare you to punch me with that new mic yew got."

"This sounds like a set up," Katy responded.

"SO EXCITED for ur performance & ur mic is EVERYTHING !! That's one of the coolest mics i've ever seen <3 xxx," yasminR_xx said.
