Listen to Rihanna on iHeartRadio

(Yahoo!) - It looks like Rihanna is brushing her teeth with jewelry cleaner these days.

The pop star recently revealed her newest asset – diamond-encrusted lower front teeth – in a photo posted on her Badgalriri Instagram page.

As the “Diamonds” singer says "cheese" for her selfie, she puckers up with attitude, commenting on her photo, “I’m an outlaw b-tch.!!”

Also in the picture, she’s sporting one of her signature midriff tops, flowing golden locks, and plenty of  glistening necklaces and bracelets.

Her reps haven’t replied to our inquiry yet to confirm whether the new dental work is permanent or removable.

But this should gain her some cool points with her fellow diamond-grilled hip-hop brethren Kanye West and Lil Wayne.
