‘Batman’ Fan Matthew Perry Called Assistant ‘Albert’

It is unclear what the mysterious nickname was in reference to, but one source claims his “Mattman” posts had something to do with a TV series idea he had in the works.

The insider told People Perry was “having fun” and was “incredibly happy” after signing on to act in a new drama film, Unworthy.

However, Perry’s ex, Kayti Edwards, claimed weeks after his death that the actor only referred to himself by the moniker when he was high.

She claimed in an interview with the UK Sun: “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.”

“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.'”
