Frankie Grande. He's the half-brother of half-wit diva, Ariana Grande Latte and was also a participant on that "reality" show Big Brother, so it makes perfect sense that he would be invited to attend a music awards show.
What doesn't make sense, though, is the Cotton Candy Troll Doll hair, or the pick jeans and the stupid black shoes. The make up, the pose; it's wrong from each and every angle.
But what really makes this a WTF moment is the shirt that he literally had painted on himself.
Child, if you cannot afford a stylist to get you actual clothes to wear, stay home.
