Just watched Dianne's vlog & her brothers one too. The creepy uncle Joe makes an appearance in Dianne's any time she tries to get a video with her grandparents, he sticks his head in the camera. It's actually quite disturbing when you know that he messages her fans, most of whom are underage girls.
Other than that Dianne's vlog was sweet, a bit cliched at the end, but still nice. She really does come across as sweet and has a good relationship with her family.
I'd say Joe was completely gobsmacked a family gathering where there wasn't a children's board/card game in sight & no Zoe to dictate the agenda of the party. All I can say is if Joe & Dianne do get married, Zoe will have a nervous breakdown at the wedding with Dianne's chaotic, noisey extended family, who by the looks of it know how to have a fun family get together.
He can put on enough strength to lift a small woman in a few months.
You are right Joe should be able to lift a small woman, but even after what 12/13 weeks of training with Strictly last year he still couldn't do full on lifts in the semi-final or final, in the salsa they lifted him cause he wouldn't have been able to pull off an impressive lift with Dianne. And as far as I can remember he started to tire towards the end of the tour & after a few near misses he did end up dropping her on her.
Edit: Her weight loss is probably to do with fitness. In that picture with her grandparents she looks "normal". But we also shouldn't shame fitness either.
I get what you mean about Dianne being a pro dancer & being extremely fit. I'm not trying to shame her fitness, I think fair play to her, going to gym doing an incredibly physical job, managing to put together & edit videos, all the while putting up with Joe. But she has lost a weight in just the last few months where it is noticeable, but as others have said before her weight probably fluctuates up & down frequently, as she has only been on YT less than year, there is nothing really to go by other than old photos.
