"[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 of occasionally splurging.

Malone, 28, also attributed more recent lifestyle changes to becoming a father.
"I guess having a baby really put a lot into perspective, and it’s really slowed me down a lot, like party-wise, you know, going out and being crazy," he told host Zane Lowe on his Apple Music show.
