Katy Perry Ditches Her Underwear On The Aria Awards Red Carpet

Oh she went there!

Katy Perry attended the 28th Annual ARIA Awards in Sydney, Australia on Wednesday wearing a showstopping look that was more than meets the eye.

The 30-year-old "Dark Horse" singer sported a provocative Jamie Lee Major two-piece that featured a halter crop top and a matching sheer mesh skirt with strategically placed black and purple floral appliqués. Despite the pretty flowers, it was pretty easy to see that Katy opted to go commando!

Just because she ditched her undies, doesn't mean the brunette babe forget to accessorize, and she did so in spades with a knotted headband by Melbourne label A-Esque, purple pumps, simple earrings, and a nose ring. To complete her dramatic ensemble, the singer sported eggplant lips and lots of mascara.

Once she was inside, Katy changed into a black strapless KTZ dress that featured white-and-gold cameos and a matching choker necklace.

Do your thing, girl!

She's got sexy in spades:
