Princess Eugenie enjoys A-list night out at Chiltern Firehouse in chic ensemble

Princess Eugenie was all smiles as she left A-list establishment Chiltern Firehouse with some friends on Friday morning. The royal, 34, is a big fan of Marylebone's grandest hotel and restaurant, where truffle pasta costs a whopping £62. It was founded by hotelier André Balazs, has seen the likes of Sienna Miller, Noel Gallagher, Lottie and Kate Moss strut onto the premises over the years. Eugenie's older sister, Princess Beatrice, is also a huge fan of the eatery and has visited several times over the years, including when Chiltern Firehouse launched in 2014.

However, her sibling did not join her on this occasion as Beatrice, 36, welcomed her second daughter Athena Elizabeth Rose with husband Edoardo Mapelli Mozzi, 41, on January 22 at 12.57pm. The baby was born several weeks early and is 11th in line to the throne, pushing her aunt Princess Eugenie down to 12th place. It was a late night out for Eugenie, who was snapped leaving the restaurant early on Friday morning looking effortlessly chic in smart casual attire.

She donned a tan-coloured overcoat along with a white button-up blouse that had intricate lace detailing along the hem.

The royal was seen strutting her stuff along the streets with her hands in her pockets alongside her pal, who clutched onto her arm. The daughter of Prince Andrew and Sarah Ferguson tucked her shirt into simple black flared jeans, to show off her slim frame.

She finished her simple, yet sophisticated look with a pair of pointed black heeled boots and a small velvet bag which she placed on her wrist. The mother-of-two swept her auburn locks into a stylish messy low bun and framed her face with dainty gold diamond earrings. Eugenie looked fresh faced, opting to wear natural makeup to the restaurant, donning a hint of mascara and eyeliner.

The youngest York sister, who appeared to be in high spirits since becoming an aunt for the third time, beamed for the cameras before setting off after a joyous night out. On Tuesday evening, she was seen in a strikingly similar ensemble as she wined and dined at a luxury French restaurant in London - just two weeks after her sister Beatrice gave birth to her second daughter. Eugenie went to La Maison Ani in Knightsbridge where a lobster salad costs £39, a bowl of truffle rigatoni costs £58 and a Veal Milanese costs £72.

In a sweet Instagram post, Buckingham Palace wrote: 'Her Royal Highness Princess Beatrice and Mr Edoardo Mapelli Mozzi are delighted to announce the safe arrival of their daughter, Athena Elizabeth Rose Mapelli Mozzi'. Last week, the Princess of York travelled to Saudi Arabia to visit The Diriyah Biennale Foundation in her capacity as director of Hauser and Wirth - a modern art gallery based in London's Savile Row.

She took to Instagram last week to share several photographs of her trip to Jeddah - which was ultimately overshadowed when Buckingham Palace announced the birth of her niece Athena. In a sweet Instagram post, Buckingham Palace wrote: 'Her Royal Highness Princess Beatrice and Mr Edoardo Mapelli Mozzi are delighted to announce the safe arrival of their daughter, Athena Elizabeth Rose Mapelli Mozzi, born on Wednesday, 22nd January, at 12:57pm.

'The baby was born weighing 4 pounds and 5 ounces. 'The King and Queen, and other members of The Royal Family, have all been informed and are delighted with the news. 'Princess Beatrice and Mr Mapelli Mozzi would like to thank all the staff at the hospital for their wonderful care. 'Her Royal Highness and her daughter are healthy and doing well, and the family are enjoying spending time together with Athena's older siblings, Wolfie and Sienna.'.

Having previously described their relationship as 'the best of friends', it is likely that Eugenie has been spending invaluable time with her sister in the post-partum period. Athena is the fourth grandchild of Prince Andrew and Sarah, Duchess of York. Their others include Princess Eugenie's sons August, three, and Ernest, one, whom she shares with her husband Jack Brooksbank. Edo also posted on Instagram to reveal his new daughter was 'tiny and absolutely perfect'.
