As the royal wedding fever swept Britain, parties were held in public spaces -- streets, squares, parks, pubs and churches, with union flags flying across the nation to mark the occasion. Local media reported over 5,500 street parties were organized across Britain on Friday.

Robyn Marchall from Australia was having a good drink with family members. "My daughter and I booked flights and accommodations for this trip on the day when this royal wedding date was announced," she said excitedly. "The ceremony is just so beautiful and fantastic. Kate looks relaxed and perfect. She is just a natural born princess."

Skepel Horn from northern Britain was dancing in the grass with friends. She said she was particularly excited because she had just seen the newlyweds at the same place where she and her friends witnessed Diana's wedding 30 years ago. "It's a way for us to recapture our youth," she said.

British Prime Minister David Cameron also held a special street party at Downing Street in celebration of the royal family's historic wedding with about 100 guests, which was completed with cupcakes baked by the prime minister's wife Samantha.
