Princess Beatrice walked the red carpet with her new boyfriend for the first time.
Photographers captured Beatrice and Mozzi arriving together at the star-studded event. Beatrice wore a belted red velvet dress, while Mozzi sported a black tuxedo.
Kate Middleton, duchess of Cambridge, One Direction member Liam Payne, retired soccer star David Beckham, designer Victoria Beckham and model Jourdan Dunn were among the other celebrities at the gala.
People said Beatrice and Mozzi were first linked in November. Sources said the pair have known each other for years and didn't require a formal introduction to each other's parents.
Beatrice split from her longtime boyfriend Dave Clark in 2016. Mozzi has a 2-year-old son from a previous relationship.
