Clint Eastwood's estranged wife has dismissed reports suggesting infidelity ended the couple's 17-year marriage, insisting she and the movie veteran have been living separate lives for some time.

Dina Eastwood has been linked to University of Hawaii basketball coach Scott Fisher since news of her split from the Dirty Harry star went public earlier this year (13), and the actor has been connected to Fisher's wife.

But Dina insists any cheating rumours are just that - rumours.

She says, "I don't think you can call any infidelity or cheating or anything like that (sic) when we're already living separately... I have no intention of ever saying that."

Dina tells U.S. chat show host Bethenny Frankel that she and Clint did attempt a reconciliation before she filed for divorce, but she now insists the marriage is over, explaining, "I don't think we'll be getting back together."
