She's signing off on this split. Dina Eastwood has filed for legal separation from her director-actor husband, Clint Eastwood.

The petition filed Monday seeks spousal support and custody of their 16-year-old daughter, Morgan. It also reveals that the two had "a premarital agreement," reports the Monterey Herald.

The couple has been married since 1996 and have one daughter together. Eastwood, however, has six other children- a daughter and son with his first wife, the four other children from other relationships.

Dina, a former newscaster, met her husband during an interview while on assignment.

The problems in their 17-year marriage reportedly arose during the filming of the E! Network's reality show, Mrs. Eastwood and Company, which only aired for one season. The show, which followed the Eastwood matriarch's life in Carmel-by-the-Sea, Calif., where her husband was mayor for two years, averaged 1 million viewers per episode.

An in-depth piece by People reveals that Eastwood was allegedly furious with his wife over the show. A source tells the publication, "It went against everything he stands for: he's incredibly private, and she put his kids on TV."

The rift between the couple grew to the point that Clint had stopped wearing his wedding ring and the two lived in separate rooms.

As with most celebrity breakup stories, the twist is this: The couple has reportedly swapped partners with another ex-couple.

College basketball coach, Scott Fisher, also a close high school friend of Dina's, was spending a lot of time in late 2012 consoling the beauty over the demise of her marriage to Clint.

Meanwhile, Fisher was finalizing his divorce from his wife of 10 years, Erica, who reached out to Clint amid concerns over Dina and Scott's friendship. Clint and Erica hit it off and by March 2013, they were dating, People reports.

Clint Eastwood is 83. Dina Eastwood is 48.
