The Hustle & Flow star's sister-in-law Yvonne Howard testified in a Los Angeles court on Tuesday (11Aug15) that she knew of the existence of a threesome caught on camera that the actor's ex, Michelle Ghent, was allegedly using to extort Howard out of money.

The movie star, who was also in court, is trying to get the divorce settlement thrown out on the grounds he signed it under duress, claiming Michelle received way more support than she was entitled to, because he was concerned about the release of personal material, according to

Even though Ghent and Howard were married for a year from 2010, she received a settlement securing her $5,800 ($3,625)-a-month for three years.

The couple divorced in 2013 and he wed his latest wife, Miranda, later the same year.
