The “Precious” and “2 Guns” actress filed for divorce from the “Blurred Lines” and “Give It 2 U” singer Friday in Los Angeles, citing “irreconcilable differences.”

The 38-year-old actress and 37-year-old singer announced they were separating in February after nine years of marriage. They have a 4-year-old son.

Patton was the inspiration behind much of Thicke’s music and appeared in some of his videos.

The crooner’s latest album, “Paula,” sold only 24,000 units in the U.S. when it was released in July. Thicke’s previous album, “Blurred Lines,” sold 177,000 units when it debuted last year.
