Princess Eugenie, the younger daughter of Sarah Ferguson (Fergie) and Prince Andrew, hosted a Disney-themed bash to mark her 25th birthday. The royal, whose actual birthday was March 23, celebrated at Royal Lodge in Windsor, her family home in Berkshire, on Saturday. For the “fancy dress” bash, Eugenie opted for a Snow White costume.

She reportedly hired small-statured actors to play her “dwarves.” Guests included members of the royal family, such as Prince Harry and Eugenie’s older sister Princess Beatrice, as well as some of Eugenie’s closest A-list friends. According to reports, the birthday girl asked her friends to don fancy dress costumes, with one exception.

“She has even written on the invitation that no one else is allowed to come as Snow White, presumably because she doesn't want any competition. But with seven dwarfs running after her, I don't think there is any chance of that happening,” an insider said.

Prince Harry turned up in a Super Mario costume, while Princess Beatrice, 26, wore a “Finding Nemo”-inspired dress, according to the Sun. Meanwhile, Fergie came dressed as Jessica Rabbit. Her sexy outfit was inspired by the cartoon character famous for her hourglass figure, a source told People.

Seven interlinked circus-style tents were set up on the grounds, housing a live DJ set, cocktail bars and chill-out zones for the revelers. A huge fairground was installed outside, including a merry-go-round and other rides and games. Among the guests who were spotted arriving were club manager Guy Pelly -- a good friend of Princes William and Harry -- and Guy’s American wife Lizzy.

Donna Air, the TV presenter and girlfriend of James Middleton, also attended. Other guests rumored to have attended included supermodel and actress Cara Delevingne and TV host Melinda Messenger. Cressida Bonas, a close friend of the birthday girl and Prince Harry’s ex-girlfriend, was also invited.

Eugenie had been living and working in New York since 2013, and celebrated her actual birthday in March in the Big Apple. She reportedly spent months planning Saturday's party to celebrate her official return to Britain.
