Post Malone, whose birth name is Austin Richard Post, added that he occasionally rewards himself with his guilty pleasure, an ice-cold soda, if he puts on a stellar performance.
"[If] I had a great show, and you know what, I’m feeling a little bit naughty, I’m going to have myself a Coke on ice," he said.
The "Better Now" rapper admitted he used to weigh 240 pounds before he cut soda from his diet. Without having the sugary drink, Post Malone said his weight dropped to 185 pounds.
