Her rep had said that she never expected an invitation, but despite that, it looks like she is pret-ty upset that she got snubbed from the event.
Here's what a friend of Royal Fergie's had to say about it:
"Sarah is devastated that she hasn't been invited. Hasn't she been punished enough by the family? Sarah is down on her luck and this is the same as kicking a person while they are down."
More from an insider:
"Sarah was hoping that the wedding would provide her with the opportunity to spend quality time with the family and prove she can and does deserve to be part of the family. Any hope she ever had of being invited back into the fold is over. Sarah might be the last person on earth to finally get it but even she knows now she's not welcome."
And more from a friend of Fergie's:
"The Duchess will be watching the wedding on television just like the rest of the world, but not from England. It will be too painful for her to be in London. She will be abroad. Once again trying to start her life knowing that kissing a prince doesn't guarantee a happy ending."
As we said before, it's sad that it's come to this, but the fact is, she betrayed the royal family last year, and this does NOT come as a surprise to us at all.
