Why are British women stereotyped as 'ugly'?

Does anyone have any insight to why this might be? And where did it come from? I was reading this news article where they was explaining how American women and Aussie women are much more attractive than 'ugly British women' even though most Americans and Australians actually decended from Britain so they look extremely alike the only noticeable difference would be their accents but Australians mainly decended from the UK. Do they just say that because they are generalizing or what? cause i have been to the uk and didn't see any ugly British girls and they was defiantly British they was not from other countries so i am confused by this
