Last night on The Voice, Christina Aguilera wore what was described by many on Twitter as a "sparkly diaper" or "metal panties":
But wake up, folks! Pretty much every other top female pop star has worn exactly those same metallic undies recently. Nicki Minaj wore them on April 6 for a Nightline taping:
Apparently Norma Kamali designed these bottoms, which have the official name of she named them "Boy Panty All Over" and are available for purchase here for $400.
You might recognize this fabric from J. Lo's latest video, "Dance Again," in which she wore the full leggings.
Gaga also prominently featured similar studded undergarments in her 2010 video for "Telephone," which look a lot like Kamali's line but are actually by Haus of Gaga.
So there you have it. Gaga set the trend, and J. Lo, Nicki Minaj, and Christina Aguilera picked it up somewhere along the way. You can't blame them — it's a damn easy way to get press.
