Is he going?: Erm, probably not, to be honest. Eugenie's 97-year-old grandfather may decide to sit out her wedding day due to some long-standing drama with her mom, Sarah Ferguson. Philip is "so estranged from Fergie," according to reports, that he will likely "decide at the 99th hour" whether or not to attend Eugenie's ceremony. Their ongoing rift — which you can read aaalll about here — even led Philip to vow never to be in the same room as Sarah again. Yikes.
