I agree Katty. Some women are called homewreckers and man stealers and whatnot, but no woman can MAKE a man have an affair/have sex with him... he has to be willing. The woman always get the shitty end of the stick when there is an affair.
As for Imogen: I think she is very pretty and attractive to look at, and in the BB house she was OK..., But the negatives (imo) are that she is pretty dull and has no talent (none that I have ever noticed anyway,) and she is another one of these banal 'famous for nothing' people.
Also, from what I have seen of her, she does not have a very high I.Q. If I were a bloke, she would just be a booty call; I can't imagine getting much intellectual conversation out of her.
