Frankie Grande Rocks Body-Painted Shirt (and Tie) at the 2014 American Music Awards [PHOTOS]

Frankie Grande gave the term "muscle shirt" a whole new meaning at the 2014 American Music Awards tonight (Nov. 23). The 'Big Brother' star and older half-brother of music superstar Ariana Grande showed up on the event's celeb-studded red carpet completely shirtless -- well, unless you count the stylish one he had body-painted on!

Frankie added a dash of formality to his faux button-down short-sleeve shirt, adding a bright pink bowtie (also of the painted variety). The tie matched the rest of his ensemble, including light pink pants and pink-tinged platinum 'do. He topped it all of with rock-star-worthy shoes and accessories.

We had to double-check that the pants were real.

A close-up look reveals no flaws. Impressive, Frankie.

We know what you're thinking: Are Frankie's abs for real or also painted on?
