Dina, 48, confirmed last week she and Clint, 83, had separated after 17 years of marriage. The couple have a 16-year-old daughter together.
"I don't like reading negative things about Clint," she tweeted Monday. "He is a wonderful, good natured, brilliant person. No matter what, I attest to that."
Clint has seven other children from previous relationships.
