Why was Fergie not invited to the wedding?

Because she disgraced the monarchy by selling their prized possessions and giving away secrets to the media so she has been shunned and stripped of her title!

She is no longer Prince William's Aunt. She was only the Aunt by marriage and since the divorce from Prince Andrew she is no longer family. Her daughters, the Princesses of York, were there however.

And to everyone saying things about the singer "Fergie", wrong Fergie.

I assume you mean Sarah Ferguson and not the singer Fergie. The royal family is still upset with her for trying to sell media access to Prince Andrew so they did not invite her to the wedding.

Fergie is no longer part of the royal family and I'm to understand she is also not on good terms with them after a scandal where she attempted to profit from selling details of their personal lives.

Because she's an ignorant tw@t that earned the ire of the Royal Family.

Sarah "Fergie" Ferguson was not there because she was invited.

Nobody from the Royal Family likes her, and they are justified.

Why the heck would Fergie be invited to the wedding?

She is not proper in any way or form.

Obama wasnt either... i agree maybe because there not british

cause the prince doesn't like latinos.lol
