The Prince of Wales attended the opening of "Sorolla: Spanish Master of Light" at the National Gallery where he was joined by Queen Letizia of Spain.
After greeting the glamorous Queen with a kiss, Charles and Letizia smiled and joked together - with an onlooker revealing Charles even looked a little 'flirty' at times!
The former journalist, 46, wore a stunning navy floral dress for the occasion, standing tall in a matching pair of point toe stilettos with her brunette tresses scraped back in an elegant ponytail.
Meanwhile, 71-year-old Camilla met with Anne, Princess Royal for Cheltenham Ladies Day.
The animal lover looked elegant and in a pristine cream coat finished with polka dot chiffon scarf.
Camilla wore chocolate toned knee high boots and matching gloves, topping off the look with a light brown fur rimmed hat.
The Duchess presented a trophy to winning horse trainer Nicky Henderson during the famous event.
