Eddie Cibrian's estranged wife Brandi Glanville wants him to pay her spousal support. reports that she has filed documents in L.A. County Superior Court claiming that the CSI star, 36, earns $60,000 a week but is only paying for her for "household bills."

Glanville, 36 - mother to Cibrian's sons, Mason, 6, and Jake, 2 - is asking for $39,963 a month in spousal support so she can pay for the kids' schooling and medical bills, among other expenses.

In August, Glanville filed for divorce after eight years, citing irreconcilable differences.

She told Us Weekly she was tired of Cibrian's infidelity. As Us Weekly first reported, he had an affair with now-single LeAnn Rimes while shooting Lifetime original movie Northern Lights, which they filmed last fall.

He recently announced that he plans to sue Life & Style for claiming that he cheated on Rimes, 27. He said the tabloid published a story "filled with inaccuracies and deceitful lies, presumably to titillate sales, but clearly resulting in harm to Eddie Cibrian and others."
