I think Cindy might be suffering from envy. Charles loves Camilla-- in all her loveliness or aged lack thereof. [Yep, Camilla's a frumpy dresser, alright. The queen is just as frumpy.]
Have you ever seen Cindy Adams? Frump meets frump. A bad case of the pot calling the kettle black. Shut up, Cindy, you're a social climbing catty woman, worse than Camilla ever could be.
