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.
Olympic-sized hug: Kate and William celebrated a victory by Team Great Britain with a rare public display of affection during 2012 Summer Olympic Games in London. The couple hugged each other after watching their home country pick up the gold in the Track Cycling event.
Shaking their groove thing: The royal couple demonstrated their dancing prowess while on the Pacific island of Tuvalu during a September 2012 Diamond Jubilee tour they took on behalf of Queen Elizabeth. Their visit also included stops in Singapore, Malaysia and the Solomon Islands.
We're expecting! After spending several days in a London hospital for treatment of an extreme form of morning sickness (Hyperemesis Gravidarium), a newly pregnant Duchess Kate checks out and heads home with Prince William on Dec. 6, 2012.
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. Kate showed off her burgeoning baby bump; she and Prince William also enjoyed themselves while squaring off in a magic duel.
Baby makes three: The new parents appear in public with Prince George the day after he was born, July 22, 2013. The couple gave everyone their first peek at the baby outside St. Mary's hospital in London.
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.
Family portrait: The duke and duchess provided the public with a long-awaited glimpse of Prince George when they released an official family photo on March 29, 2014. The portrait, which also included the family dog, Lupo, was the first time the baby had been seen since his christening five months earlier. The photo was taken by the same photographer hired for the baptism ceremony.
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. The duke and duchess also engaged in some playful competition during a pair of yacht races and spent time at the local zoo with their son.
