Stephen Collins of 7th Heaven Divorcing; Wife "Devastated" and "Exhausted"

Actor says in statement he and Faye Grant "are moving forward separately in our lives" and will "go through this process in a way that honors or family"

One of TV's most famous dads and his real-life wife are calling it quits.

Stephen Collins, former star of 7th Heaven, told E! News in a statement Monday that he and wife Faye Grant "are moving forward separately in our lives."

"She has been my dearest friend and a loving mother," said Collins, 64.

He and Grant, who married in April 1985, are parents to a daughter named Kate. "I know that we'll go through this process in a way that honors our family."

Meanwhile, no one sounds more surprised than a very tired Grant about what happened.

"Stephen's filing for divorce is a surprise. I am devastated," she tells E! News. "I wish him the very best in whatever path he chooses to take. Twenty-seven years of marriage inHollywood is the equivalent of 189 dog years. I was exhausted."

In addition to Collins' starring role as the Rev. Eric Camden on 7th Heaven from 1996 to 2007, Collins appeared on Brothers & Sisters, Private Practice, The Three Stooges and The Office.

Grant, 54, is an actress; she starred on ABC's V and played Tattie McKee in State of Grace from 2001 to 2002.
