Katya is good choreographer but her behaviour is not professional, the apology was no doubt rung out of her to save her job, shame for her partner. Sean obviously not bothered about his girlfriend, but she's made a meal out of it, that relationship couldn't have been right.The one that ruins it for me is Oti, you can't shut her up, she wants all the limelight, dancing manically about and screaming when interviewed, that's never right. I love the dancing and all the others in the show, but I do think fame has gone to the heads of the couple mentioned.
