In their first public outing since returning from their honeymoon in the Seychelles last month, the Duke and Duchess of Cambridge - popularly known as Prince William and Kate Middleton - showed up for the Epsom Derby, a prestigious horse race.

The Saturday June 4 afternoon race took place at Epsom Downs, near London. The couple attended, People.com reported, in support of Queen Elizabeth's horse, Carlton House, a favorite to win, but instead placing third.

The Duchess' parents, James and Carole Middleton, also attended the event in support of a horse that came in fourth place.

The newlyweds' last sighting was a behind-closed-doors meeting with President and First Lady Obama when they visited the United Kingdom in May.

The Duke and Duchess of Cambridge are scheduled for an 11-day visit to North America that includes stops in Canada and Los Angeles.
