The singer, who reportedly spends two hours at the dentist prepping before red carpet events because she's terrified of having bad teeth, didn't have much to worry about last night because there was a gold grill covering her pearly whites.
"Tonight's custom #ROAR GRILL courtesy of the FAMED @tvjohnny shout out to @cstonethebreadwinner as well!!!" Katy captioned the picture she posted of herself wearing the grill.
The designer also posted a picture of himself posing with Katy at the rehearsals, where she was wearing gold chains on her neck and wrist and a "Roar Industries" sweatsuit.
Obviously, Katy ditched the dental apparatus later in the night when she performed her new hit single live for the first time, but we think the blinged-out accessory was still fun while it lasted.
What did you think of Katy's grill?
