Princess Beatrice and Mary McCartney enjoy night out in Mayfair

Princess Beatrice was spotted enjoying a night out at exclusive Mayfair private members’ club Oswald’s on Monday night. 

The 33-year-old royal, who gave birth to her daughter Sienna in September, looked casual in a denim jacket and black floral headband, as she left the exclusive club – a favourite with the royals – following a Monday night soiree with photographer Mary McCartney.

The high profile pals left separately, with Beatrice catching a ride in a chauffeur-driven car – complete with baby seat in the back – from the glitzy London nightspot.

Mary, 52, daughter of Paul McCartney, left shortly after Beatrice – sporting a striking grey track suit. The famous snapper wheeled along a silver case, and carried a black clutch bag in the other hand

Mary, 52, exited the A-list night spot shortly after. The famous snapper, wearing a metallic grey track suit and white trainers and her brunette locks tied back in a ponytail, was seen wheeling along a small silver suitcase as she made her way to a waiting car. 

The club on Albemarle Street in Mayfair is famous among wine connoisseurs, and is owned by fellow environmental activist Robin Birley, whose father named his famous members’ club Annabel’s after his socialite wife – Lady Annabel Goldsmith.

Prince William, who was seen enjoying a night with friends at the club in November, is also said to be a member of 61-year-old Etonian Birley’s secretive member’s only club 5 Hertford Street. 

Joining costs £1,800 a year and members – rumoured to include Harry Styles, Margot Robbie, Mick Jagger and numerous royals – need to be recommended by a proposer and a seconder. 

At the Platinum Jubilee Thanksgiving service just over a week ago at St Paul’s, royal Beatrice raised a smile with her choice of bag – the designer clutch was clearly emblazoned with the words ‘Wifey for Lifey’. 

A breather? New mum Beatrice left husband Edoardo Mapelli Mozzi in charge of their eight month old daughter Sienna

The friends appeared in high spirits as they left the Mayfair club on Monday evening 

The daughter of Prince Andrew and Sarah Ferguson wore the embellished Sophia Webster blue bag as she walked hand-in-hand into the London church with her husband of two years Edoardo Mapelli Mozzi.

The £350 sold out bag, which according to the website was designed for modern brides, is made from pearlescent PVC and has a glittered border in blue. 

The couple welcomed their first child, daughter Sienna, in September and following the Thanksgiving service, Edoardo gushed about his wife – and sister-in-law Eugenie – on Instagram.

Posting two photos of his wife online, the father-of-two wrote: ‘My wonderful sister-in-law and phenomenal wife looking so stunning.’

It comes after royal authors said Princess Beatrice is stepping into the limelight to ‘help her grandmother the Queen’ following her father’s downfall and is ‘much more confident’ after becoming a wife and a mother.
