The 56-year-old producer told Spanish newspaper El Mundo she is "less visible" than the couple because she never had an interest in fame. Diandra is Michael's first wife; she and the actor married in 1977, and filed for divorce in 1995. She was awarded an estimated $45 million in the settlement, plus homes in Beverly Hills and Majorca.
"I don't believe in showing off," Diandra declared. "I've never sold photos or kept money from anything and I've always given everything away to charity."
"I'm proud to be able to say that I've never turned my private life into show business," she continued. "Too much public exposure affects children."
Michael and Catherine have been together since March 1999, and married in November 2000. The couple have two children together, 14-year-old son Dylan Michael and 11-year-old daughter Carys Zeta, and Michael and Diandra have a 36-year-old son named Cameron. Michael and Catherine separated in May 2013, but reconciled six months later.
