Happy anniversary, William and Kate! It's been three years since Prince William and Kate Middleton said "I do" in the royal wedding seen 'round the world. We couldn't get enough on April 29, 2011, as we pulled an all-nighter in California to watch Kate unveil her stunning Alexander McQueen gown and see the two newlyweds seal their union with a Buckingham Palace balcony kiss. Luckily, after the wedding celebrations ended, we got a lot more of the Duke and Duchess of Cambridge — and their adorable son, Prince George. With appearances in the UK and on their royal tours to North America, East Asia, and, most recently, Australia and New Zealand, they've been showing off their royal love all over the world. See some of their sweetest public displays of affection as husband and wife — and new parents — now!
