Matthew Perry’s ex, Kayti Edwards, is speaking out following the traffic death of the “Friends” star.

Kayti, a former model and Julie Andrews’ step-granddaughter, reportedly dated Perry in 2006. In a new interview, she claims that his final Instagram photo of him relaxing in his hot tub could be a sign that he was “not sober” at the time of his passing.

“I know Matthew and I know that he wouldn’t have just drowned,” she told the UK Sun on Saturday. “I think he might have taken pills in the week leading up to this.”

Perry was found dead of an apparent drowning at his California home on Oct. 28. He was 54. A bystander, who TMZ reports was his assistant, found him submerged under water and he was unresponsive before first responders arrived on the scene.

No illicit drugs were found at his residence aside from some prescription medications. His cause of death is still listed as “deferred” and no foul play is suspected. The coroner ordered more tests, including for toxicology.

Perry said in 2021 that he was sober and that he estimated he spent nearly $9 million trying to get clean throughout his life.

Edwards claims, however, that “things aren’t adding up.”

“He was paranoid and would take them all, so there wasn’t any evidence, and then go out for more when he was ready to,” she alleged of his past use.

She also alleged that his last Instagram post — which was him eerily in his hot tub with a mention of “Mattman” in his caption — was allegedly a tell that the late actor was using illicit drugs.

“That Mattman thing was not something he did when he was sober. Mattman would come out when he was not sober and he felt kind of invincible,” Edwards claimed to the outlet.

“I was around when he was getting high, although I was not getting high with him, and when I would say maybe he should cool it a little bit with the drugs, he would say, ‘No, I’m Mattman.’”

“He had a thing with water when he was doing drugs,” she claimed, alleging that he once was found “naked and high” in a neighbor’s swimming pool and that he was “always alone” when he did drugs.

The Post reached out to Perry’s rep for comment.

Perry often spoke out about his drug and alcohol struggles through the years. While promoting his 2022 memoir, “Friends, Lovers and the Big Terrible Thing,” he noted that he was “grateful” for co-star Jennifer Aniston because she would reach out to him the most.

Aniston — alongside Courteney Cox, Lisa Kudrow, Matt LeBlanc and David Schwimmer — paid tribute to the late star at his funeral in LA on Nov. 8.

Days earlier, his friend Athenna Crosby, 25, who was one of the last people to see Perry alive, insisted that the actor was “100 percent” sober before his tragic passing.

“In the interaction that I had with him, he was extremely positive, sober, acting normal, spoke very well, did not give me any impression that he was under [the influence of] drugs or alcohol of any kind,” she told Fox News Digital earlier this month.

“So, I think people are speculating that this was a relapse situation,” she added. “I just want to defend him and say that it was not.”
