Adrienne Maloof's hopes of saving
her marriage have taken a drastic turn for the worse.
Husband Paul Nassif, a Beverly Hills plastic surgeon who had sought legal separation
from the Real Housewives of Beverly Hills
star last month, now wants a divorce.
Citing irreconcilable differences, Nassif, 50, has requested joint legal and physical custody of their kids, Gavin, 9, and twins Christian and Collin, 6, according to documents filed Tuesday in L.A. Superior Court.
Married in 2002, Maloof, 50, recently told PEOPLE of the marriage: "We're at that point where it's that bump in the road, [but] we're trying to work things out. I always like to keep a positive attitude and hope that we can resolve our differences."
