Dina Eastwood filed for legal separation from her husband of more than 17 years - Oscar-winning actor Clint Eastwood - Monday in Monterey County Superior Court, ABC News has confirmed.
The petition for the civil case lists attorney C. Michael McClure as filing on behalf of Dina Eastwood.
In August, multiple outlets reported that the couple, who reside in Carmel, Calif., had been living apart.
The couple met in 1993, when his wife - then known as Dina Ruiz, a TV news anchor - was assigned to interview the legendary actor-director. The two married on March 31, 1996.
Last year, Dina Eastwood, 48, starred in the reality show "Mrs. Eastwood & Company," which included a mix of her work managing the a cappella group Overtone and running her household. Clint Eastwood, 83, didn't appear much on the program.
People magazine reported that the show had put a strain on the marriage. Being a private person, Clint Eastwood didn't want to see his children on TV.
Despite her filing for a legal separation, Dina Eastwood took to Twitter last week to express her support and gratitude to the "Dirty Harry" actor.
"I don't like reading negative things about Clint," she tweeted. "He is a wonderful, good-natured, brilliant person. No matter what, I attest to that."
This is Clint Eastwood's second marriage. He was married to Maggie Johnson from 1953 to 1984. Eastwood has a total of seven children, including, Morgan, his daughter with Dina Eastwood.
ABC News reached out to reps for both the Eastwoods, but neither would comment on the legal separation.
