According to exclusive documents obtained by The Blast, Gayheart filed Friday in Los Angeles County Superior Court. She is asking for joint legal and physical custody of the couple's two minor children, 7-year-old Billie and 6-year-old Georgia.
Gayheart is also seeking spousal support.
The couple was married in 2004. The documents list the date of separation as "TBD."
Gayheart is well known from her commercials as the Noxzema girl, as well as the "Scream" movie franchise. She also made headlines with Dane in 2009 when a sex tape of the couple with another woman in a bath tub was leaked online.
According to an interview about when the couple first met, Gayheart says: "It's probably one of the least interesting stories in the world. It went basically like this: 'You wanna go out?' 'Yeah, sure.' Ten months later, we were married."
