Rihanna Shows Off Diamond Grill (PHOTO)

Never one for subtlety, Rihanna sports a bra top, body chain and some flashy mouth bling in one of her latest Instagram selfies. "I'm an outlaw bitch!!" the 25-year-old songstress modestly captioned the photo.

RiRi is no stranger to grills. In 2011, she released a clip of herself getting fitted with a mouthpiece for her "You Da One" video.

Rihanna isn't the only fan of bejeweled teeth. According to a report from TMZ Tuesday, Amanda Bynes has commissioned a new grill resembling that of Miley Cyrus (wait, didn't Amanda call Miley "ugly" in a recent tweet?).
