The wheels are back in motion to put the brakes on Clint and Dina Eastwood's 17-year marriage. says Dina filed for divorce Tuesday citing irreconcilable differences. 

She had inexplicably withdrew legal documents asking for a formal separation last month but the new documents filed Tuesday indicate she's ready to pull the plug on the relationship.

TMZ says Dina is seeking full custody of their 16-year-old daughter Morgan, who was featured on her E! reality series "Mrs. Eastwood & Company."

She's reportedly also looking for spousal support and for Clint to pay attorney's fees.

Clint has seven other children from previous relationships.
