Disora is Jewellery according to the trademark. I think Bradley is into business stuff so he’s probably doing that for herI think Bradley goes between Alex’s houses, Dubai and the US where his fiancé lives. (Perrie must really get along with him for him to own 25% of whatever Disora is).
I’ve heard Perrie refer to Ellie as her PA a couple of times, so when she’s working (like I think she has been this week) then I get why she’s there. Sometimes I think it’s all slightly weird until I remember Alex and Perrie don’t really live together if they’re both working so I understand having other people around.
