The 7th Heaven star wed actress Grant in April, 1985, but the pair has now decided to call it quits.

The 64 year old tells Entertainment Tonight, ""My wife and I are moving forward separately in our lives. She has been my dearest friend and a loving mother. I know that we'll go through this process in a way that honours our family.""

The former couple share one child, daughter Kate.
