Princess Eugenie celebrated her 26th birthday with friends on Wednesday. The British royal, known for her love of crazy fascinators and headgear, sported rabbit ears and posed with a friend.

The princess celebrated her special day with friends and silly hats. Eugenie ushered in her birthday with friend and TV host Poppy Jamie, who shared a picture of the pair of them sporting a flower headdress and rabbit ears on Twitter. “When a sunflower and rabbit celebrated one of the best chicks birthday,” she captioned the picture.

The eighth-in-line to the throne is a huge fan of costume parties, and last year celebrated her birthday with a Disney-themed party. She reportedly dressed up as Snow White for the event. Her cousin Prince Harry sported a Super Mario costume, and her sister, Princess Beatrice, wore a Finding Nemo inspired gown.

Prince Andrew and his former wife Sarah Ferguson’s daughter, who is also associate director of the Hauser & Wirth art gallery in London, has been rubbing shoulders with celebrities lately. The brunette beauty gave actress friend Michelle Trachtenberg an art tour at the Hauser Wirth & Schimmel gallery in Los Angeles. The Gossip Girl star took to Instagram and posted a snap with friends at the gallery.

“Let the art tour continue....last week we went to The Broad museum, today I got a tour of the brand new Hauser Wirth & Schimmel gallery in downtown LA featuring’ Abstract Sculpture by Women 1947-2016’…” she captioned the picture. Eugenie wore a white sleeveless dress with high neck.

It featured a fitted bodice and flared, pleated skirt. She accessorized with small drop earring, ring and a black and delicate gold bracelet. Eugenie had a black and white cross body bag slung over her shoulder.

Her short tresses were kept in a side part and she wore sunglasses with blue mirrored lens. She posed with Michelle and three more friends in the picture.
