At Joe had the sense, to have the make over done on Dianne and not him. The minions would have reacted like savages and would be accusing the poor girl of trying it on.
My God though, could Joe have gotten anymore childish, the poor girl felt do rushed, you could see throughout the video Dianne was being supportive, like when Joe called Flo out for making a mistake, Dianne tried to say it was because of how she was holding her lips, and was encouraging, but then at the end, she had to stroke Joe's ego, by telling him his was really good, it's like seriously does Joe really need to feel that is make up skills are as good as as a 17 year olds. Dianne really didn't need to stroke his ego and how supportive she was to Flo during the make over was ruined by her then stroking Joe's ego.
As for doing the podcast as well as the musical, I did read on Twitter, so this may not be accurate and I'm not from the UK so don't know for sure, that there is no guarantee that Joe will actually appear in every show, as the cast preforming is only announced the day of each show and that Ashley didn't do nearly all the shows in her run, her understudy did. So if this is true he may only appear in 3-4 shows a week.
As for the podcast, I hate to say it, as Joe has turned into such a dick, but this type of media will probably suit him and he can't do any worse the woman who did it last year, she was God awful. It will also keep the minions who got interested last year because of Joe, to stay watching.
