The 29-year-old notably skipped two very important events.
The first was her "dear" relative Lady Gabriella Windsor's wedding to Thomas Kingston last Saturday.
She then decided not to go to the Chelsea Flower Show.
Many were surprised since it is a favourite for the royals and her entire family stepped out to support Kate Middleton's submission into the show.
Princess Eugenie then shocked everyone, when she stepped out to go for dinner at George Restaurant in Mayfair, in London.
Her appearance had many in a flurry, especially when it was observed that Eugenie was holding a bouquet of flowers.
The royal swiftly moved over her stomach the moment she was snapped by British photographers.
Eugenie was all smiles as she went about her evening.
One person even took to Twitter about bumping into the Princess.
Twitter user Jai'me Jan shared his experience.
"I just met the lovely Princess Eugenie at a party and had a chat with her! She was absolutely lovely!"
He added: "She was so so charming."
His friend even took a sly snap of the pair talking.
Fans have publically voiced their hopes for news of her to share a pregnancy announcement.
"Cant wait till we get a Royal Baby Brooksbank announcement. You're my favourite royal couple," one fan gushed.
In the UK, fans are so sure that Prince Andrew's daughter is pregnant that bookmakers have slashed the odds on Eugenie and Jack confirming that they are expecting a baby.
The odds are now at 1:4 with bookies expecting an announcement any day now.
“It looks like the Royals are getting broody,” Alex Apati of Ladbrokes told The Sun.
What’s more, the royal dropped a hint on Instagram earlier this year.
Eugenie shared a snap of her engagement to Jack captioning it, “What a year it’s been since then and how exciting for 2019.”
