Beatrice, 36, attended a star-studded party at celeb hotspot Chiltern Firehouse restaurant in Marylebone, London on Thursday night. She joined other famous faces such as Ellie Goulding , Sienna Miller, Lily Allen and Noel Gallagher, while Strictly host Claudia Winkleman was also there with her husband, Kris Thykier.

Beatrice looked stylish in an all-black ensemble - wearing a velvet blazer with a cinched waist and wide-leg trousers. She sported glam make-up, had her red hair down and looked in high spirits, beaming as she left the popular venue, which was holding a party to mark the restaurant's 10th anniversary. Ellie Goulding turned heads at the event, looking incredible in a black mesh corset dress, with a thigh-high split.

She also wore a black Venezian-style mask and a pair of towering black heels. Lily Allen, meanwhile, stunned in sheer white gown with corset and lace details and Sienna Miller showed off her fashion credentials in a black and gold dress. Beatrice's night out comes after Buckingham Palace issued a statement on Tuesday announcing that she and husband Edo Mapelli Mozzi, 40, are expecting their second child together, with the baby due in ear.
