Now, we all know that the guest list is über-exclusive (not even Barack Obama made the cut), but did Brit native Sir Elton John—and tight chum to Princess Diana—receive his fax yet?
And what about William's father's good friend Joan Rivers, did she get her invite from Buckingham Palace?
"We're not holding our breath," Melissa Rivers told us, not sounding hopeful at all.
No way! But we thought your mom was so close to Prince Charles, we exclaimed with disappointment.
"She is," sighed Melissa. "But look, I think the parents at this wedding—and their friends—are way down on the list."
A friend to Sir Elton hinted pretty much the same thing.
"Elton's said he doesn't expect to be invited," relayed the knighted pal's bud, "and as far as I'm aware, he hasn't received a fax."
Shame, really, as new daddy-Elton recently reminded us all that he was besties with Di, and even performed at her memorial service.
But he was also quick to let us know he didn't think his friendship with Di warranted an invitation:
"I think because of my relationship with Princess Diana," John told reporters recently, "people automatically think I'm going to be invited."
"I just wish them the happiest of lives together," Sir Elton elaborated. "[Kate and William] seem very happy. He's a really terrific man, William, and he's going to be a great king."
Hmm. If Sir E. isn't gunning for an invite, then why would he refer to William as the future king, when William is, in fact, second in line to the throne?
Perhaps he's not the only commoner who wants William to be next in line...
Remember, even Di said she felt Charles wouldn't get the job.
