However, the 'Teenage Dream' singer - who was married to the comedian at the time - burst into tears and left the studio, much to the surprise of Mills and his team.
"Something was up - I couldn't put my finger on it but she seemed on edge," Mills told The Sun. "Anyway, we thought it would be funny to get a Russell Brand lookalike to surprise her.
"Well, she ran out of the room screaming. My producer told me she was in tears in the next room, while I tried to smooth it over with viewers.
"I have no idea why it freaked her. For all I know they were having marriage problems. But she eventually did come back on screen. When there was a break she whispered in my ear, 'You better play my songs forever!'"
He added: "Looking back, we were pushing our luck."
Russell Brand and Katy Perry eventually split up a year after the incident, with their divorce being finalised in July 2012.
Scott Mills releases his autobiography Love You Bye today (August 30).
