Superstar DJ Calvin Harris is taking his former financial adviser to court, accusing him of siphoning $22.5 million into what his attorneys call a failed real-estate development scheme.

In an arbitration demand filed in Los Angeles Superior Court on Sept. 12 and obtained by The Post, Harris — whose legal name is Adam Richard Wiles — alleged the adviser Thomas St. John, who managed his finances from 2012 until April 2025, “systematically” took advantage of their relationship to secure millions for a project dubbed CMNTY Culture Campus in Hollywood. 7
