Princes Eugenie of York turns 23 on 23 March, and the fun-loving royal will doubtless celebrate the day with those closest to her.
Last year saw Eugenie mark her big day with a dinner for her inner circle at the exclusive Hakkasan restaurant in Mayfair.
This time around, the low-key group is likely to include her cousin Prince Harry, 28, and his new girlfriend Cressida Bonas, who is 23.

Eugenie played matchmaker for her relative and her society friend Cressida who, as the daughter of Curzon banking heir Lady Mary-Gaye Curzon, is used to mingling in royal circles.
The trio have recently skied their way around the Swiss Alps and partied together during a fun-filled night out at London's Rum Kitchen.
Eugenie's birthday is likely to be the next stop on their social itinerary. Sister Princess Beatrice, and mum Sarah, Duchess of York will likely also be at any events, as will boyfriend Jack Brooksbank.
