Her elder sister Princess Beatrice is regularly spotted on the London society scene with boyfriend Dave Clark.
But as a student at Newcastle University, we're not used to seeing Princess Eugenie out very often with her long-distance love, waiter Jack Brooksbank.
A low-key couple in comparison to Beatrice and Dave, the young lovebirds reunited in the capital last night for a spot of rock 'n' roll.
Low-key: Princess Eugenie and her boyfriend Jack Brooksbank leave the Paul McCartney Teenage Cancer Trust charity concert at London's Royal Albert Hall
However, they declined to pose up for photographers and kept their distance as they left the venue.
Eugenie, 22, and Jack, 26, joined her mother Sarah Ferguson at the Sir Paul McCartney gig at London's Royal Albert Hall.
The star-studded gig, which also saw performances by The Who's Roger Daltrey and Rolling Stone Ronnie Wood, was raising money for the Teenage Cancer Trust.

Eugenie is currently in her third year of a combined honours degree in Art History, English Literature and Politics at Newcastle University.
Living up north means she and Jack conduct a long-distance for much of the year as he is based in London.
The couple have been quietly dating since Spring 2010 after meeting on holiday in Switzerland.
The pair were introduced through friends in Verbier where Eugenie was celebrating her father Prince Andrew's 50th birthday.
Who said romance was dead? It wasn't just the two of them though, her mother Sarah Ferguson came too
Long-distance love: Eugenie spends most of the year in Newcastle, while Jack lives in London
Their romance started shortly after Eugenie split from Sir Richard Branson's nephew Otto Brockway - half-brother of Kate Winslet's new boyfriend Ned RockNRoll - after six months together.
Eugenie and Jack were first photographed together at the Cuckoo Club in London in May 2010.
In January this year, they enjoyed a romantic holiday in Mustique in the Caribbean.
Although he currently works as a waiter in a London bar, Jack attended the £27,000-a-year Stowe public school in Buckinghamshire.
His parents, chartered accountant George and Nicola own a holiday home near Bordeaux, France.
