Princess Beatrice , who is expecting her second child with husband Edoardo Mapelli Mozzi , showed no signs of slowing down as she mingled with a host of celebrities on Tuesday evening. The 36 year old royal, who announced her pregnancy earlier this month, was all smiles as she attended two back-to-back events in central London, rubbing shoulders with the likes of Nicky Hilton and Lady Kitty Spencer. The first event was the launch of a new capsule clothing collection by Nicky, in collaboration with Australian designer Rebecca Vallance, at Mayfair hotspot Gaia.

For the occasion, Beatrice showcased her own fashion sense in a stunning black dress with statement bow details, which elegantly skimmed her baby bump. The collection, consisting of 31 pieces including evening gowns, party dresses and jumpers, is perfect for the festive season, according to the Daily Mail - and may have given Beatrice some inspiration for her Christmas wardrobe. Following the conclusion of the event, there was no downtime for Princess Beatrice as she dashed to her next engagement—a dinner at The Orangery, hosted by Estée Lauder and Harrods.

She was accompanied by none other than Princess Diana's nieces , Lady Kitty Spencer and twins Lady Amelia and Lady Eliza Spencer, turning the evening into an impromptu family gathering! The Orangery is also noted for its location near Kensington Palace, once the residence of Prince William , his wife Princess Kate , and their children Prince George , Princess Char.
