I haven't been a big fan of Cheryl's as I think she relies far too much on the sex factor and it's getting old.
It worked with Christian, Gilles and a few of the others because there was an actual chemistry there. Unfortunately, I see zilch chemistry with Cheryl and William.
I think that William is an attractive man, but I just don't find him at all sexy. And, I just don't care for this pairing at all. Sorry.
