CLINT EASTWOOD'S WIFE
FILES FOR DIVORCE

EXCLUSIVE

Clint Eastwood's wife, Dina, has filed for divorce ...

Dina -- for some reason -- withdrew the legal docs she filed last month, asking for a formal separation.  But on Tuesday, Dina filed for divorce based on irreconcilable differences.

In the docs, Dina is asking for full physical custody of their 16-year-old daughter Morgan.

Dina wants spousal support.  And, of course, Dina wants Clint to foot the bill for attorney's fees.

The couple was married in 1996.  Clint has 8 children, but 7 are from previous relationships.
