Arguably, Prince William and his wife, Catherine Middleton (affectionately known as Kate), are one of the most famous couples in the world. Since getting married in front of millions on April 29, 2011, the pair have welcomed three adorable children—Prince George, Princess Charlotte, and Prince Louis—and are super hands-on parents.

As their relationship continues to evolve, and William prepares to one day take on the major role of king, the public displays of affection that he and Kate were more freely able to indulge in when they were dating have become somewhat reduced. While we have no doubt that the couple are still very loved up, given the serious nature of The Prince of Wales' future position, they've definitely taken a step back when it comes to things like hugging, or stealing a cheeky peck, in front of photographers.

In the spirit of celebrating their relationship and how far Will and Kate have come together, we've rounded up our favorite photos from their early days, featuring some excellent outfits and lots of flirty vibes (obsessed).

In 2002, they moved into a student house with two other friends and it's believed that by Christmas 2003, romance blossomed after Kate split from a previous boyfriend. Here are the happy pair looking very much in love on the day of their graduation ceremony on June 23, 2005.

    During their whirlwind recce of the United Kingdom, a soon-to-be-wed William and Kate tossed pancakes for Shrove Tuesday and greeted crowds in Belfast.
