Princess Eugenie made an appearance at Poppy Delevingne's 40th birthday celebration in London on Thursday evening, her growing baby bump clearly visible beneath a black dress paired with a vibrant purple jacket.
The 36-year-old royal, who is expecting her third child this summer, was accompanied by her husband Jack Brooksbank for the occasion.
Her elder sister, Princess Beatrice, also attended the festivities, arriving at the venue alongside her husband, Edoardo Mapelli Mozzi.
Both York sisters appeared in high spirits despite the ongoing difficulties surrounding their parents, Andrew Mountbatten-Windsor and Sarah Ferguson.
