Eugenie's absence from yet another key occasion is sure to raise eyebrows among royal fan watchers who are convinced Fergie's daughter is expecting her first child with husband Jack Brooksbank.
And that's not the only clue the Princess is pregnant.
Eugenie has been sharing a slew of social media throwback photos from her childhood in recent weeks, and has remained out of the spotlight save for a single panel appearance in connection with the charity she co-founded, The Anti-Slavery Collective, last week.
Princess Eugenie shared five photos from the event for which she donned a decidedly loose fitting grey top that hid her figure completely.
The pictures immediately sparked a storm in the comments section with one user declaring: ‘I think I see a baby!’
Balmoral would be the perfect place for an announcement.
A place of happy memories for Eugenie, the Princess used to regularly journey to to the castle with her parents Prince Andrew and Sarah, Duchess of York.
‘I think Granny is the most happy there. I think she really, really loves the Highlands,’ the young royal revealed in TV documentary Our Queen at Ninety in 2016.
