Princess Eugenie’s sister Princess Beatrice is reportedly feeling left out.

Prince Andrew and Sara Ferguson’s daughters Princess Beatrice and Princess Eugenie attended a Celine Dion concert in London’s Hyde Park for the British Summer Time Festival. Princess Beatrice was photographed with a glass in hand and she was said to be intoxicated as the night went on, leaving some of her friends concerned that she might be “out of control,” New Idea reported.

While some would think of it as Princess Beatrice just having a bit of harmless fun, sources close to the princess claimed that she’s "feeling left out." Her cousins Prince William and Prince Harry already have a family. Her younger sister Princess Eugenie is already married and is expected to announce her pregnancy soon.

“Desperate to marry her beau Edoardo Mapelli Mozzi, Bea feels worried that her commitment-phobe boyfriend may soon dump her and leave her forever single,” an insider said.

“Beatrice is desperate to get married as soon as possible and is already trying to fall pregnant. She wants a family and doesn’t care if she’s pregnant when they walk down the aisle – even though this would be heavily frowned upon by the senior royals. However, the truth is, we could have a royal shotgun wedding on our hands.”

However, Princess Beatrice also doesn’t want to give her boyfriend an ultimatum because the last time she did that to an ex, it backfired to her. She was in a 10-year relationship with Dave Clark, but when she asked him about their future plans including marriage, it ended up in a split.

“Bea doesn’t want to put the pressure on Edoardo, but now time is running out, and with her sister’s pregnancy news, she feels under the pump and at a loss if he doesn’t pop the question,” the source added.

Back in June, Princess Beatrice and Princess Eugenie had a double date. In the snaps, it’s clear that Princess Eugenie approved of Mozzi for her sister because he was photographed holding Princess Beatrice and Princess Eugenie’s hand while walking.

Also, back in March, Princess Beatrice and her boyfriend were joined by the Duchess of York on a fun outing. They were spotted at Annabel’s private club in Mayfair.
