Let's just say Rihanna's new look is not her sexiest. The normally sultry star shows off her new dental grill in a sneak peek at her upcoming video "You Da One," Yahoo! reports.

The grill appears to be gold and covers only the lower half of her mouth. And if you're worried that the grill has permanently changed Rihanna's superstar smile, well, don't be. In the video, which shows her getting fitted for the accessory, Rihanna says, "I'm getting a grill made for an upcoming video shoot." Which implies that AFTER the video shoot, she'll be grill-free again.

Grills have seen their share of popularity in the hip-hop community. Kanye West has had one. And Lil Wayne's is permanent. During an interview with Jimmy Kimmel, he said, "The grills ... the grills, they come out. These don't, I'm going to die with these. So these are my teeth. I can go to the dentist and switch them out, but it's surgery."

Back to Rihanna, her single "We Found Love" held the top spot on the Billboard Hot 100 singles chart for the eighth-straight week, making it the longest-running No. 1 single of her career. Let's hope she doesn't want to win the record for the longest-running grill. Unless you think it's flattering?
