Adrienne Maloof & Hubby's Open Marriage Led To Divorce, Claims Pal

By Amber Goodhand - RadarOnline.com News Editor

Adrienne Maloof and her husband filed for separation on Monday, but RadarOnline.com has exclusively learned the couple were having issues for a long time and even had an open marriage.

The Real Housewives of Beverly Hills star's estranged hubby Dr. Paul Nassif has already moved out of the family mansion, but friends of the couple are not surprised by the split and even say they saw it coming.

"Adrienne and Paul have pretty much had an open marriage for quite some time," a close pal exclusively told RadarOnline.com.

"They both knew of indiscretions the other had, and both would get jealous, but their marriage had become so broken it was the only option for them."

After nine years of marriage, Adrienne exclusively told RadarOnline.com: "I'm so sorry that this is happening, but my children are my life and sometimes we need to do what's best for them. It's an unfortunate situation, but I have to have my kids' best interest at heart."

The cast of the hit Bravo show is taping tonight and insiders say Adrienne's divorce is sure to play a key role in the new season.

"Everyone involved in the show knew Adrienne and Paul weren't happy with each other and quickly on their way to a divorce," the source continued.

"Having an open marriage was not a solution but they were desperate to keep it together for the children."

While the source maintains an open marriage existed between Adrienne and Paul, they note that neither is actually ending the marriage because of a new relationship.
