Kelsey Grammer's third wife is pulling the plug on their 13-year marriage, just in time for her to be on a show about housewives. Camille Donatacci Grammer's lawyer filed a divorce petition on Thursday, citing that old chestnut "irreconcilable differences," TMZ is reporting.

Donatacci, a 41-year-old former Playboy model and dancer, is seeking joint legal and physical custody of their their children, 9-year-old daughter Mason and a 6-year-old son Jude. She married the 'Frasier' actor in 1997, a year after they met at a party thrown by MTV.
