I see you've been reading Yahoo OMG news. I went to The Sun website to read Price's column and she did spell it correctly - heifer not heffer. But the morons that write for OMG are barely literate, their dictionary consists of "omg lol, girl crush, well jel, gorge, amaze and Cheryl Cole". So even a stupid tabloid has better editors than Yahoo celebrity news.
To answer your question, no, I don't agree with Katie Price and I think she messed up big time here. Expect to see her soon apologising for it, blaming the paper for twisting her words or something. I think Price is a really insecure and lacks self-esteem, that's why she seeks attention in the way she does and lets all those men take advantage of her. She needs to work on her issues. No amount of plastic surgery, marriages to toyboys or babies will make her feel more worthy, it needs to come from herself. We should be sorry for her, really. I agree with you that Kelly Brook is hot, but even if she wasn't, KP should not have said that. How either of them looks is not the point here at all.
