It's almost show time!
The twosome arrived in a chauffeur-driven car around 7:30 p.m. with their wedding party, which included Prince Harry, 26, and Pippa Middleton, 27. The rest of Kate's immediate family -- including her parents, Michael and Carole, and brother James -- were also in attendance.
Earlier in the day, Kate, 29, was spotted entering Clarence House through the visitors entrance (she's still a visitor at the royal residence until Friday). When she emerged around 4 p.m., she carried a sizable brown cardboard box -- contents unknown -- into the trunk of her Audi A3.
"Everyone's happy," a Clarence House worker told Us Weekly late Wednesday. "The atmosphere is really great!"
