The beachfront kingdom has crumbled. Linda Thompson, the mom on FOX's new reality series The Princes of Malibu, is filing for divorce from her husband and costar, composer David Foster, the Associated Press reports.
The cause of the split "will remain personal and private," said the 55-year-old Thompson, a former Miss Tennessee who was previously married to Olympic gold medalist Bruce Jenner. In a statement, she added, "It is important to remember that real life is not to be confused with art or entertainment."
The Malibu-based FOX show tracks Thompson's 21-year-old and 23-year-old sons Brody and Brandon Jenner as they frequently clash with their Grammy-winning stepdad.
The couple's 22-acre Malibu estate, featured prominently in the show, has been sold and the profits will be divided equally, according to papers filed in Los Angeles Superior Court on July 11.
