The 25-year-old, who recently split up with the Prince, was spotted on a night out with his cousin Princess Beatrice and her boyfriend Dave Clark in London last night.
Meanwhile, Princess Beatrice opted for a long-sleeved cream top paired with a floor-length navy skirt and metallic pink clutch bag.
The pair were joined by Princess Eugenie at Mayfair members' club Annabel's where conversation no doubt turned to Prince Harry - after all, it was Eugenie who originally introduced the couple.
However, given he reportedly "hooked up" with a wealthy socialite at friend Guy Pelly's wedding in Memphis recently it seems the reality is maybe this relationship is over for good.
Whatever happens, here's our two thoughts: 1. Cressida is amazing at evening wear (seriously - and we thought Glastonbury 2013 was her fashion moment). 2. Big blow-dries are always, ALWAYS, a brilliant idea.
