Princess Beatrice has always been close to her younger sister, Princess Eugenie. But a palace insider claims that Prince Andrew’s daughters are currently at odds, and the reason might have something to do with a certain royal protocol.

Recently, there have been reports saying that Beatrice’s relationship with Edoardo Mapelli Mozzi seems to be getting serious. Mozzi was already introduced to Beatrice’s parents, Prince Andrew and Sarah Ferguson, and he even went along with his girlfriend’s royal family on a trip to Bahrain, which naturally sparked speculations that their engagement is just around the corner.

Meanwhile, there were also speculations that Eugenie might be about to make an exciting announcement of her own. After her marriage to Jack Brooksbank in 2018, royal family watchers believe that a pregnancy announcement is also in the offing.

If these happened in a regular family, it would mean double the fun as both sisters have something to celebrate. But in the royal family, announcing both events simultaneously is not an option, according to royal expert Phil Dampier.

Speaking to New Idea, Dampier explained that the royal family always coordinates major announcements of its members, such as weddings or pregnancies, so they won’t “steal each other’s thunder.”

But if speculations on Beatrice and Eugenie are true, it is highly likely that the latter’s news would take precedence since pregnancy is a time-sensitive issue. “If Eugenie is pregnant it wouldn’t surprise me if Beatrice delays any announcement about her wedding until after her sister has shared her joyous news with the world,” Dampier told the publication.

That just might be the case if New Idea’s sources and Beatrice are reportedly not pleased about it. “Beatrice is furious at Eugenie and tension is at an all-time high between the sisters, we’ve never seen them fight so badly,” New Idea quoted an unidentified tipster.

The source added that Beatrice resents the fact that she has to plan her wedding to Edo around her sister’s pregnancy announcement as if the latter’s matter is more important. “This is supposed to be Bea’s big day —the fairytale wedding she’s been dreaming of since she was a little girl — and now it’s been pushed aside because of Eugenie’s baby,” the source said. “It’s just not fair.”

Beatrice might have been accommodating to her younger sister in other matters, but she allegedly won’t yield so easily when it comes to her wedding plans. “And while Bea usually bites her tongue and plays along, she’s not doing that this time,” the tipster claimed. “She’s told Eugenie just how unhappy she is and is not taking this lying down. It’s caused quite the stir in the palace.”

At the moment, however, there’s still no official confirmation on whether Beatrice is indeed planning to tie the knot or if Eugenie is indeed already pregnant. For now, all these remain to be speculations.
