Terrence Howard's Ex-Wife Wins Appeal, Spousal Support Decision Reversed

Terrence Howard's taking an "L" in his longstanding spousal support war with his ex-wife ... who just won in appeals court.

According to court docs, Michelle Ghent Howard got a ruling on their spousal support overturned. Two years ago, Terrence convinced the court he'd been forced to sign their marital settlement under duress. He claimed she was threatening to go public with naked photos and videos.

At the time, he'd been paying her $5,800 per month.

Michelle appealed that ruling and the judges agreed with her argument -- that Terrence was NOT under duress because too much time had passed between the threat and Terrence signing the agreement. The court said it was more like Terrence had "buyer's remorse" -- and he had other options besides signing on the dotted lines.

For instance, the court said he could have gone to the police if he felt Michelle was blackmailing him.
