He may be known as Taylor Swift's boyfriend to some but Calvin Harris is a success in his own right. The Blame hitmaker has been named the highest-paid DJ in the world for the third year running.

According to Forbes, Harris, 31, earned a staggering $66m (£41.7m) in the last 12 months, putting him at number one on their Electronic Cash Kings 2015 list. The Scottish musician is believed to have earned the bulk of his income from performing live shows, which includes a residency in Las Vegas and appearances at music festivals around the world, in addition to endorsement deals and his lucrative contract with Emporio Armani as an underwear model.

In June 2015, it was revealed that the Summer chart-topper and his pop star girlfriend Swift managed to trump spouses Beyonce and Jay Z as the highest-paid couple in, music with combined earnings of $146m. When he was crowned the top-earning DJ for the first time in 2013, Harris told Forbes: "The rise of dance music has been astronomical... I happened to be in the right place at the right time."
