Kate Moss and Count Nikolai von Bismarck made a rare public appearance as they stepped out to support Annabel’s Art Auction.
The notoriously private couple looked loved-up as they attended their first event since Princess Eugenie’s star-studded Royal Wedding, to help raise money for Teenage Cancer Trust.
Moss, 44, looked stunning in a sleek black maxi dress with a cinch waist, complete with gold embellishments for Wednesday night's bash.
Bismarck complemented her look and opted for a classic black suit and a pop of colour with a pale orange shirt.
The couple appeared in good spirts as they posed for snaps side-by-side ahead of the evening.
They were later spotted cosied up together as they sat at a table ready for the auction.
Moss and Bismarck first sparked speculation of a romance in 2015 and are believed to have been quietly dating on and off for over two years.
Other names at the A-list bash included Mamma Mia! star Lily James, who ditched her trademark blonde locks for her natural brunette tresses.
James appeared alongside The Crown star and boyfriend Matt Smith, who sported a sleek navy suit for the occasion.
Princess Beatrice also turned out in full-force for the event wearing a dazzling red velvet midi dress and black heels.
Jay Rutland, Tamara Ecclestone, Sadie Frost, Jodie Harsh and Abbey Clancy and her husband Peter Crouch were also in attendance.
