William and Kate sealed their love with not one but two kisses on Buckingham Palace's famous balcony.
Some 500,000 well-wishers roared their approval outside the palace and along The Mall as the newlyweds exchanged their first kiss.
Many in the crowd were shouting "kiss, kiss", as the bride and groom appeared with their families.
And then as an RAF flypast swept towards the palace, the couple kissed for a second time. Never before had they displayed such affection to each other in front of the world.
Body language experts said the kisses showed a "deep love" between the royal couple, while many watching the scenes on large television screens in Hyde Park were left clamouring for a longer embrace.
After leaving Westminster Abbey, the couple were taken by horse-drawn carriage to Buckingham Palace as up to one million well-wishers along the route cheered them on.
As their carriage arrived at the palace, a sea of people followed them down The Mall. Eager for a glimpse of the royal couple on the palace's balcony, many pressed against its ornate iron gates. The bride appeared to mouth "Oh wow" as she stepped out and was greeted by a vast crowd of flag-waving people.
And as the crowd demanded that all-important clinch, the bride and groom happily obliged, with William saying: "Let's kiss." They both leaned in for their first loving kiss - a brief one which left bashful William appearing to go a little red afterwards.
Just two minutes later, William turned to Kate, after encouragement from excited bridesmaid eight-year-old Margarita Armstrong-Jones, and appeared to say: "One more kiss?" The second kiss was longer, with the bride giggling and raising her shoulders afterwards, while shy William grinned broadly, appearing to say "That's it" to the crowds.
After a moment on the balcony alone, as they turned to return indoors, William touchingly took his new wife's hand. They headed back inside together, Kate giving one last smile and glancing over her shoulder at the rapturous scenes.
