Lily Collins and Jenna Coleman share a joke at Cartier Queen's Cup Polo in Windsor

One’s currently conquering TV period drama in Victoria and the other’s a starlet of the silver screen in Hollywood.

So there was plenty to ruminate about between Jenna Coleman and Lily Collins on Sunday, as they attended the Queen’s Cup Polo Final at the Guards Polo Club in Windsor on Sunday, surrounded by various other celebrities and one or two royals.

The pretty brunettes looked chic in pastel tones as they joined to catch up at the event, hosted by Elizabeth II herself. The event is one of the top five polo tournaments in the world – attracting the biggest names in the game and their impressive pony power. The prestigious polo show, held annually, is named in Her Majesty’s honour and attracts guests from society’s highest echelons.
