Dina Eastwood has no ill will toward her estranged husband, Clint Eastwood.
Despite living apart for some time
and recently Tweeting about "new beginnings," the former Mrs. Eastwood & Company
star, 48, let people know Monday she has nothing but respect for her ex.
"I don't like reading negative things about Clint," she Tweeted
of the 83-year-old Hollywood legend. "He is a wonderful, good natured, brilliant person. No matter what, I attest to that."
The pair, who called it quits after 17 years of marriage, "were great partners for many years," a source told PEOPLE last week. "This is really sad."
