In New York's Times Square, hundreds gathered at six in the morning to watch the royal nuptials on the big screen.
"I don't think we'll forget it!" the bride laughed.
Meanwhile, early birds paid $150 a piece for a special royal wedding breakfast at New York's Palace Hotel. Channel 11 anchorwoman Jodi Applegate wore her own wedding dress to cover the event.
The celebration included a huge wedding cake and life-size cardboard cutouts of the bride and groom.
And in San Francisco, women gathered at three in the morning for a royal wedding party!
They wore Kate Middleton engagement ring knockoffs, sipped pink champagne, and changed into satin pajamas and tiaras in time for the magical moment.
