Princess Beatrice hit the town on Tuesday, attending two events in London. King Charles' 36-year-old niece stepped out for a cocktail party hosted by Nicky Hilton and Rebecca Vallance to celebrate the launch of their Nicky Hilton x Rebecca Vallance Collection at Gaia Mayfair. The Princess, who is expecting her second child, looked chic wearing a black midi bow dress.

Beatrice wasn't Prince William's only cousin at the events on Tuesday. Princess Diana's stylish nieces Lady Eliza Spencer and Lady Amelia Spencer were at both the dinner and cocktail party wearing dresses from Rebecca Vallance's Nicky Hilton holiday capsule collection. Amelia opted for the Alivia Long Sleeve Mini Dress, while Eliza sparkled in the Leyla Long Sleeve Midi Dress. The twins were joined by their older Lady Kitty Spencer at The Orangery for the Estée Lauder Re-Nutriv Dinner.

Beatrice's pregnancy was revealed by Buckingham Palace earlier this month. "Her Royal Highness Princess Beatrice and Mr Edoardo Mapelli Mozzi are very pleased to announce that they are expecting their second child together in early spring; a sibling for Wolfie, aged eight, and Sienna, aged three," the palace said in a statement, adding: "His Majesty The King has been informed and both families are delighted with the news."

The royal baby will be born 11th in line to the throne. Beatrice and Edo, who celebrated four years of marriage in July, welcomed their first child together, daughter Sienna Elizabeth Mapelli Mozzi, in 2021. The Princess is also a stepmother to her husband's son Christopher Woolf, nicknamed Wolfie, from a previous relationship.
