Just about anybody can gain a couple thousand followers on Instagram or Twitter. But becoming a "social media queen" is no easy feat.

Demi Rose Mawby, British model and self-proclaimed "world's sexiest DJ," has done just that. The Birmingham-born beauty has amassed nearly 5 million followers on Instagram since launching her account just four years ago at the age of 18.

The 22-year-old—who maintains a strict diet and fitness regimen to maintain her stunning figure—has since been pursuing a career in lingerie modeling and music.

Here are some of Mawby's sexiest photos.
