I do think there is a certain karma about AT. She treated her first dh like shit and GB has done the same to her.
I think she comes across as very unlikeable. Sinitta, on the other hand, I've always thought of as rather vacuous. She only seems to be in the newspapers on holiday with Simon Cowell. However she really did well and tried her best and came across really well. AT isn't interested in doing her best, she is interested in beating people whatever it takes.
