Time flies when you're having fun! Prince William and the former Kate Middleton celebrate their third wedding anniversary on Tuesday. Here, they kiss on the balcony at Buckingham Palace on April 29, 2011.

In the three years since Prince William and Duchess Kate became husband and wife in front of millions of adoring fans, they've only become bigger world superstars. 

Add in their adorable baby, Prince George, and the trio are unstoppable.

On Tuesday, the Duke and Duchess of Cambridge celebrate their third wedding anniversary. Becoming first-time parents last summer hasn’t stopped the sweet moments between these college sweethearts, who just returned from a whirlwind tour Down Under, their first trip abroad as a family.

Here are some of the sweetest moments from William and Kate, the couple the world just can’t seem to get enough of. 

Connecting in Canada: Just a few months after their wedding, the newlyweds left for Canada on their first overseas trip together. Their journey took them everywhere from Prince Edward Island to the Northwest Territories. On July 8, 2011, the lovebirds donned matching white Stetsons while attending the Calgary Stampede parade.

Expelliarmus! The adorable couple got into character during an April 26, 2013 tour of London's Warner Bros. studio, where they were joined on the "Harry Potter" film set by fellow muggle Prince Harry.

Proud parents: Prince William and Duchess Kate got to show off their pride and joy, for the first time since his birth, at his Oct. 23, 2013 christening at St. James Palace. The occasion marked the first time the world got to see the now-famous set of chubby cheeks belonging to Prince George. The family posed later that day for their first set of formal family portraits with celebrity photographer Jason Bell.

Down Under: Duchess Kate and Prince William brought Prince George with them on a three-week tour of New Zealand and Australia earlier this month. The trip gave an eager public ample chances to see the royal couple as hands-on parents, but it also gave the young pair plenty of alone time.

Picture perfect: Photos captured the couple taking a romantic stroll in front of the iconic Ayers Rock, where they posed at the same spot as William's parents 31 years earlier during a similar tour by Prince Charles and Princess Diana.
