Adrienne Maloof and Dr. Paul Nassif have each filed for divorce.

The Real Housewives of Beverly Hills star and her husband each separately filed for divorce from one another after 10 years of marriage on Tuesday, Us Weekly reported.

According to Us sources, the couple cited irreconcilable differences in the filings.

Nassif reportedly filed for legal separation from his reality TV star wife on July 30, stating he wanted joint legal and physical custody of their three boys.

Maloof told RadarOnline at the time she thought the separation was best for nine-year-old Gavin and her six-year-old twins Colin and Christian while she and Nassif were trying to figure things out.

As for what went wrong in their relationship, the taping of The Real Housewives of Beverly Hills' upcoming season was apparently very demanding and tiresome for both Nassif and Maloof and put stress on their marriage. Cheating or other love interests reportedly have nothing to do with the split.
