Music producer Calvin Harris prefers to keep his success under wraps by refusing to flash his high earnings. The DJ, who has made an impressive $1.6 million (£1.1 million) from just one of his five companies, CH Music, in the last year alone prefers to be subtle with his cash. A source tells Britain's The Sun newspaper, "Calvin has done extremely well. In the past few years, he's gone from a relatively successful music producer to one of the highest earning DJs on the planet. "Things like his Las Vegas residency and worldwide mega hits such as We Found Love with Rihanna will have ensured millions in the bank account. He's not particularly flash with it either, you don't see him rolling around clubs with loads of diamonds and magnums of champagne."
