Which Celeb Has a Spiked Silver Dress?

This starlet's sexy gown could double as a weapon

Don't get too close to this singing sensation...she's got spikes on her metallic minidress!

The pop star wore this crazy custom creation when she hit the carpet at the VMAs in New York.

She even twittered about it before wearing it out: "Ladies lock up ur husbands, girls grab a hold of your boyfriends...You ain't never seen a dress like dis!!! So fresh I HAD to have it made!"

Think you know whose dress doubles as a weapon? Find out after the jump...

It's Katy Perry, who's never afraid to experiment with her style.

She also wasn't afraid to come her to friend Taylor Swift's defense after Kanye hijacked the mike during her acceptance speech.

"F--K U KANYE," she posted. "IT'S LIKE U STEPPED 0N A KITTEN."

Well said, Katy!
