Gold grills made our list of the worst trends of 2013, but Katy Perry is determined to keep the look alive in 2014. Case in point: She rocks the most over-the-top mouth piece in the trailer for her "Darkhorse" music video. The singer, who plays "KatyPatra" in the clip, sports the craziest grill we've ever seen to complement her equally eye-catching makeup and costume.
This isn't the first time Katy has tried the trend. She wore a grill that spelled out "Roar" to the MTV Video Music Awards last year (photo six) — and we thought that was shocking!
