Matthew Perry's colleagues and family are said to be "blindsided" by the recent arrest of his personal aide Kenneth Iwamasa in connection with a drug inquiry.

The US Weekly reported that a source shared, “Matthew kept secrets," adding, "I wouldn't be surprised if Kenny was the only one who knew how bad things were."

According to the insider, Iwamasa first worked with the Friends star in June 2022 after previously working for producer Doug Chapin, Perry's manager, for some time.

They added, “When they brought in Kenny they thought he would be a great fit because he worked for Doug for years.”

A source continued, “When he was brought on it was already chaotic. Matthew wasn’t actually sober. He had been going in and out of sobriety. And multiple people were helping to take care of him.”

“Kenny knew the situation and could deal with Matthew,” the insider revealed.

As per a source, Iwamasa was a trusted member of Perry’s team, they said, “When Matthew’s [previous] assistant left they didn’t hire a new one for a while. Matthew wasn’t acting at the time so someone was needed only to handle his life and around the house.”

The Los Angeles Police Department revealed in May that they had initiated an investigation into Perry's death. The investigation specifically aims to uncover how Perry obtained the ketamine that was found in his body when he passed away.
