Princess Eugenie and Jack Brooksbank attend London art party amid engagement rumours

Princess Eugenie and her longtime boyfriend Jack Brooksbank enjoyed a fun night out in London on Tuesday (Oct. 4). The couple, which has been the source of swirling speculation over a potential engagement, put the speculation behind them as they attended the Serpentine party in South Kensington.

Eugenie, who works as an associate director at an art gallery, beat the chill in a black military-style coat. She and her beau were pictured enjoying an evening at Albert's Club, a new venue located a stone's throw away from Eugenie's home.

EUGENIE AND JACK'S LOVE STORY IN PHOTOS

The 26-year-old and her long-term love Jack recently spent a long weekend at Balmoral, where they visited Eugenie's grandmother the Queen.

Jack has briefly met the 90-year-old monarch before but the invitation to stay for a prolonged period of time at Balmoral – one of the Queen's favourite retreats – was a sign of Jack and Eugenie's solid relationship.
