Tyler Perry is facing an accusation of sexual assault — a claim coming from an actor on his long-running TV show, “The Oval,” and one Tyler’s camp calls a “scam” … TMZ has learned.

Derek Dixon filed a lawsuit against Perry, and in the docs he claims he and the director met at an event back in 2019 — in Derek’s words, Tyler picked him out of the crowd and asked for his phone number, suggesting he might have a role for him.

As it turns out, he did … Derek says Tyler gave him a small role in 2 episodes of a show called, “Ruthless.”

Shortly thereafter, Derek says he landed the role of Dale in “The Oval” — great for his career, but he claims it was around this time that Tyler also started firing off sexually suggestive texts … including asking what Drew’s sexual preferences were, and telling him he has sex with men.

Derek also notes his character, Dale, was written as a gay, homeless and desperate store clerk who had to sleep with other characters for a place to stay. He claims that’s exactly what Tyler told him he was looking for in a real life sexual partner … someone who would be loyal and dependent upon Tyler.

Derek says he feared his career would be derailed if he flatly rejected Tyler — so, instead he told him he just wasn’t “the sexual type” … but he was always terrified he’d lose his job if he complained of sexual harassment.

To that point, he says Tyler, once again, invited him to Atlanta later in 2020 … and things allegedly took a dark turn. Derek claims Perry greeted him warmly, but quickly started a sexually charged conversation — like asking him if he “likes it rough in bed” — and then grabbed Derek by the throat while saying, “Look how excited you just got.”

He says he pushed Tyler away, and that was the end of that alleged incident.

The lawsuit includes years of text messages allegedly sent by between both men — most of the ones Tyler allegedly sent are sexually charged … for instance one reads, “No straight man would be going on walks with you or cooking dinner for you unless they wanted to f**k you. I would f**k you.”

The most aggressive incident allegedly went down in June 2021, again at Tyler’s Atlanta home — Dixon was staying in the guest house and wearing only his underwear, when he says Tyler came in to give him a goodnight hug.

He alleges Tyler yanked down his underwear, groped his butt and said, “Relax and just let it happen” and assured him it wasn’t going to hurt. Dixon says he managed to rebuff this advance by changing the subject.

According to the suit, Dixon finally filed a complaint with Equal Employment and Opportunity Commission in June 2024, and then quit “The Oval,” saying he could no longer put up with the alleged sexual harassment.

Dixon is suing Tyler and Tyler Perry Studios for quid pro quo and workplace sexual harassment and sexual assault and battery … and he’s seeking $260 million in damages.

Tyler’s attorney Matthew Boyd tells us, “This is an individual who got close to Tyler Perry for what now appears to be nothing more than setting up a scam. But Tyler will not be shaken down and we are confident these fabricated claims of harassment will fail.”
