maloof230.jpg Real Housewives of Beverly Hills star Adrienne Maloof has filed for divorce from husband Paul Nassif after nine years of marriage, according to online reports.

The papers were filed in Los Angeles, with Maloof citing "irreconcilable differences" as the cause for the split. The reality star and her plastic surgeon ex share three children together.

Both wealthy in their own right, Maloof reportedly has an airtight pre-nup that protects her massive family fortune, so it's unlikely there will be spousal support requests. Custody may be an issue, however, as Nassif has filed his own divorce petition requesting join legal and physical custody of the kids, according to TMZ.

It remains unclear whether the breakup of their marriage will be a plot line on the upcoming season of the Bravo reality series.

Such sad news!
