Most disliked words of phrases

I just saw a headline about Anthony Armstrong Jones and his regular affairs. It said he had a secret 'love child' while married to Princess Margaret.

All three of my children were 'love children' but I was married to their father i.e. my husband. I really dislike the accepted idea of a 'love child' as the product of an illicit affair. What does that say about the child or children conceived and born within the marriage?
