It’s official – a livid DINA EASTWOOD has formally filed for divorce in court after second-guessing herself.

The actor’s wife of 18 years halted their split via a request to dismiss the petition for legal separation that she had originally filed back in September.

However, Dina the former TV actor and star of the reality series star of “Eastwood & Company” filed again on Tuesday, citing irreconcilable differences.

She is seeking full physical custody of their 16-year-old daughter Morgan and wants spousal support.

As The ENQUIRER previously reported Eastwood — who has eight children — is lavishing gifts and cash on his latest lady love – a blonde hottie half his age.

In  a love triangle shocker that we first reported, Clint is dating 42-year-old Erica Tomlinson-Fisher who is the ex-wife of the man who Dina has turned to in the wake of her split, ex-Australian basketball star Scott Fisher.
