21 of 143: 'Real Housewives of Beverly Hills' star Adrienne Maloof's husband Paul Nassif filed for legal separation on Monday, July 30.

Nassir, who filed the legal documents in Los Angeles Superior Court, cited irreconcilable differences as the reason for the split, according to People magazine. He is seeking joint physical and legal custody of their kids - 9-year-old Gavin and 6-year-old twins Christian and Colin.

Maloof and Nassir wed in May 2002. There is a prenuptial agreement in place, but it is unclear as to who will receive what in the separation.

Maloof, 50, is the daughter of a billionaire, while Nassif is a wealthy plastic surgeon, who has appeared on the E! Network's 'Dr. 90210.'
