I think there are 'inaccuracies' (to put it kindly) in that report. It mentions that Artem has been signed up as a choreographer for the next series of So You Think You Can Dance, but also says he has signed up for a second series of Strictly. I very much doubt that second statement is true, since the producers won't even know if the series will be re-commissioned yet, let alone have started signing up pro dancers or even presenters.
And 'Kara is spending all her time with Artem', is she? Well, not terribly surprising if they're rehearsing for the show, is it? I have no idea if this is a romance, showmance or just wishful thinking on the part of the media, but given that this is the Daily Star, I don't give the story a lot of credence.
