I can't decide. Some time ago there was a vlog where SJ took us all along with her to get new glasses (spectacles). When she got home to explain to the other Lalalanders on the frames she chose she said "Philip liked them". A strange thing to say unless he was a "significant other"? Then the matching rings happened.... but then they always have separate rooms when the go away.....as far as we are lead to believe anyway....I’ve always believed they were sleeping together too. When do you think it started? My guess is around Halloween last year.
