Grillz gone wild! Gold grills are getting a glamorous makeover courtesy of some of music's hottest divas -- most notably, Beyonce and Rihanna!

Mrs. Carter recently posted on her Tumblr a striking image of her gazing at the camera, her makeup soft and flawless, her hair wavy and loose, her teeth…bedazzled and gold! Turns out her vampire-chic fanged grills are for her new "Bow Down" video, but they're so pretty and stylish they could be on a fashion runway.

Rihanna's new grill, meanwhile, is decidedly less dainty. On Wednesday, Aug. 7, the singer, who's been partying it up in Barbados this week, shared on Instagram a shot of her new golden grill in the shape of a machine gun, captioning the pic "Up watching Cocaine Cowboyz #KillinDeseHeauxz #phuckyogrill #ilickthegunwhenimdonecuziknowthatrevengeissweet." (She captioned another photo in which she's licking her grill "she + AK.")

Tell Us: Who has the better grill: Beyonce or Rihanna?
