If what insiders out of London are saying is true, there will be a Duke and Duchess of Sussex-sized gap on the guest list of Princess Beatriceโs wedding to Edoardo Mapelli Mozzi next year.
โTension has been brewing between Harry and Meghan and the York girls for months now,โ one palace source tells Womanโs Day exclusively.
โBeatrice has confessed to friends that if she gets her way, they wonโt be invited.โ
Itโs believed the rift began when Beatriceโs younger sister Princess Eugenie, 29, was privately miffed that Meghan, 38, debuted her baby bump during her own nuptials last October, effectively stealing her thunder.
And ever since then, itโs been a social media tit for tat between the houses of Sussex and York.

โAs soon as Harry and Meghan officially confirmed their pregnancy via Instagram as they began their tour to Australia days after Eugenieโs wedding, youโll recall that her mum [Sarah Ferguson] dropped a treasure trove of Eugenieโs wedding pics just hours after,โ our source adds. โIt was obviously done on purpose as revenge.โ

And now, it seems the war has escalated again.
Just 24 hours after Meghan and 34-year-old Harry gave the world an incredible glimpse of their son, Master Archie, during their trip to South Africa, the Yorks struck again, sharing a picture of Edo and 31-year-old Beatrice showing off her brand new art deco-style diamond dazzler.
โThe timing of Beatriceโs announcement was incredibly rude, given it stole the spotlight back from the important causes Harry and Meghan were trying to promote,โ says a source. โOf course, they were furious, but itโs the kind of pettiness theyโve come to expect these days.โ

โEdoโs a private citizen, so technically she can forgo the traditional royal wedding for something low-key. That way she wonโt have to invite Harry and Meghan and worry about all eyes being on them instead of the bride and groom!โ
