One of MGK’s trademarks is not to wear a shirt. He loves flaunting his skinny chest and tattoos. The rapper has more ink than a stationary shop but we’re not sure if he successfully pulled off this outfit. However, we give him credit for being himself and not caring what anybody else thinks.
Meanwhile, he has his arm around Fox in a possessive manner. It looks as if he’s refusing to release her as she clutches his hand. Fox is also several years older than Kelly so it’s possible that he felt safe with her. We’re not going to get into Freudian power dynamics but there could be something there (via The Brag).
