I’d normally agree, but I think there is a difference between lying about writing a book or £50 Advent Calendars etc. and keeping a relationship quiet for a bit - especially in the early days when you don’t know whether it has legs. So if he’s employing a little misdirection on the relationship, it’s okay. I think they both need time after Strictly to work out whether they could have a proper relationship without all the Strictly stuff going on, and them just getting back to their normal lives. Then, if they decide to make a go of it, then tell viewers.
