Maxim may 2015 Issue # 203 Covergirl: Charli XCX Charli XCX is the latest pop starlet to cover the latest issue of Maxim magazine! For the Tetsu Kubota-photographed black + white editorial spread, the singer looks her sultriest as she dons a simple yet curve-hugging dress. Inside the issue, it states: "The hard-driving 22-year-old pop phenom Charli XCX is one of the brightest stars in the music business. And she's just getting started." And we totally agree with that testament.
