If you don't have something nice to say, don't say anything at all. Dina and Clint Eastwood may be separated, but Dina, for one, isn't about to badmouth her ex -- and won't tolerate anyone else doing so, either. On Monday, Sept. 2, less than a week after confirming exclusively to Us Weekly that she and her husband of 17 years had separated, the former TV news reporter, 48, took to Twitter to defend the Oscar-winning actor and director, 83, in the wake of their split.

"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."

In fact, Dina told Us last week that she and the Dirty Harry actor remain close, even though they've been living separately for some time. (A source told Us the couple split more than a year ago, in June 2012. "Clint fell out of love with Dina a long time ago," the insider shared, noting that the separation was "amicable.")

Married since March 1996, Dina and Clint Eastwood have one daughter together, 16-year-old Morgan. The Trouble With the Curve star is also dad to seven other kids, including two with first wife Maggie Johnson, and a daughter, Francesca, with Titanic actress Frances Fisher. Francesca, Morgan, and Dina appeared together on the E! reality series Mrs. Eastwood & Company, which ran for one season in 2012.

Eastwood himself has yet to comment on the split. (A manager for the Hollywood legend, when contacted by Us for comment, said only, "I know nothing about that.")

Dina, though, is looking forward to the future -- however uncertain it may be. A few days before confirming the separation to Us, she tweeted this: "Darkness somewhere means light somewhere else. #newbeginnings."
