Clint Eastwood dating former wife of his wife’s new beau

LOS ANGELES — Randy Hollywood icon Clint Eastwood has jumped on the exes-go-round along with his estranged wife, Dina — just days after she announced that their marriage was on the rocks.

The Oscar-winning tough guy was photographed with stunning blonde Erica Tomlinson-Fisher, 42, whose ex-hubby, Scott Fisher, has been dating Dina since her split from Clint.

Sources said the Eastwoods’ 17-year marriage unraveled after Dina starred in a reality show over his objections.

“Clint didn’t want to have anything to do with it,” a source told The Post today about “Mrs. Eastwood & Co.,” which ran from May to July 2012 on the E! Network.

Dina announced this week that the couple had separated in June 2012, but she quickly rebounded into the arms of Fisher, 50, a pal since high school and the hoops coach at the University of Hawaii, according to Us Weekly.

And while Dina, 48, was seeing Fisher, the 83-year-old Eastwood put the moves on Tomlinson-Fisher.

“After Scott and Erica divorced, Erica was sure Scott was romancing Dina,” a source told US. “Erica called Clint’s office last February to discuss her suspicions — then he fell for her!”

Dina at first expressed shock over the swap.

“I am saddened to see photos of Clint with Ms. Tomlinson-Fisher. I look forward to new beginnings,” she told Us.

Later, she did a 180 and tweeted, “I don’t like reading negative things about Clint. He is a wonderful, good-natured, brilliant person. No matter what, I attest to that.”

Dina, sources said, has been spending time in Hawaii with her hunky new boyfriend, a former pro basketball player in Australia.

But she is now believed to be in Carmel, Calif., with daughter Morgan, 16, her only child with Clint.

Clint is directing “Jersey Boys” for the next two months in LA.

Both Fisher and Dina grew up in Fremont, Calif. and went to Mission San Jose HS together.

The reality show chronicled the lives of Dina and daughters Morgan and Francesca, 20 — Clint’s daughter from an earlier relationship.
