I genuinely don't really care about either of them as individuals and don't find her attractive in the slightest and he can't sing to save himself but I will say one thing.
She is one smart business woman. There's a raft of girls wanting to be like her and 99.9% of them have a fraction of her success, publicity, wealth, exposure (how ever you want to describe or measure it it)
I have saw their programme once or twice (I know!) and what came across to me was how good they were with their kids especially him with the one that's not his.
I really think it's a publicity stunt though. ITV might not give them another tv series, he's got a new album coming out! mmmmm I wonder!
