Kate Middleton and Prince William Together in Public Again: A Timeline of Their Evolving Love Story

A royal love story for the ages! Kate Middleton and Prince William are going strong and celebrating 13 years of wedded bliss. 

The couple's wedding anniversary was on Monday, April 29, just weeks after the shocking announcement that the Princess of Wales has been diagnosed with cancer. 

After months of speculation, Kate went public with the news in March 2024, opening up about her private battle and how she and William have handled the situation with their three young children. And after six months away from the public eye, Kate made her triumphant return at the 2024 Trooping of the Colour looking radiant as ever.

The couple has more than a decade of marriage under their regal belts, share three kids -- Prince George, Princess Charlotte and Prince Louis -- and are next in line to the British royal throne after King Charles III and Queen Camilla. 

But when the Prince and Princess of Wales first met, they were two lovesick college students at the University of St. Andrews in Scotland. They went from friends and roommates to longtime loves in a matter of years. 

In the wake of Kate's recent diagnosis, look back at a timeline of their real-life romance:

2001: College Freshmen

Though they'd go on to have a happy life together, when William and Kate met at the University of St. Andrews in Scotland as college freshmen, they were simply friends at first. 

"We were friends for over a year first and it just sort of blossomed from then on," William shared in the couple's engagement interview with ITV years later. "We just spent more time with each other and had a good giggle, had lots of fun and realized we shared a lot of the same interests. She's got a really naughty sense of humor which kind of helps me."

Kate noted that it took "a bit of time" for her and her future husband to get to know one another, adding, "But we did become very close friends from quite early on."

2002: Roommates

Still just friends, the schoolmates moved in together with a group of friends, including Fergus Boyd and Olivia Bleasdale. William later shared that the romance "blossomed from there." 

During this time, Kate also modeled in a student fashion show, which is rumored to have been where she caught William's eye as possibly more than a friend. The future Princess of Wales wore a sheer dress by peer Charlotte Todd as a part of the assignment appropriately titled, "The Art of Seduction." 

In 2019, Kate revealed that William used to cook her dishes in college to impress her. 

"[In our] university days, he used to cook all sorts of meals," Kate said. "I think that’s when he was trying to impress me. Things like Bolognese sauce and things like that."

2004: Going Public

After keeping things private for more than a year, William and Kate's romance was thrust into the public eye in 2004 after photos were printed in The Sun of the couple on a ski holiday in Switzerland. The headline "Wills gets a girl" sent shockwaves through the royal world as the royal family threatened to boycott the British tabloid for breaking the agreement to give the family privacy following a public photo call with William, Charles and William's younger brother, Prince Harry.

2007: A Split

The couple broke up for several months between April and June. William spoke about the decision during the couple's engagement interview years later, saying, "We did split up for a bit. We were both very young. It was at university, and we were both defining ourselves as such and being different characters. We were finding our own way… it soon worked out for the better."

Kate added that she "wasn't very happy" about the split at the time, but ultimately felt that it was a good decision for their relationship. 

"It made me a stronger person. You find out things about yourself that maybe you hadn't realized," she shared. "I think you can get quite consumed by a relationship when you're younger and I really valued that time for me."

The couple was overjoyed to announce their engagement publicly just a few weeks after William popped the question while on holiday in Kenya. 

"We had a little private time together with some friends and I just decided that it was the right time, really. We'd been talking about marriage for a while so it wasn't a massively big surprise," William admitted during the couple's engagement interview. "I took her up somewhere nice in Kenya, and I proposed." 

"It was very romantic. There's a true romantic in there," Kate said of her future husband, adding that the proposal was a "total shock." 

William said that despite the surprise nature of the proposal, the couple had been discussing marriage for "a while."

"It just felt really right. I had been doing a bit of planning because I wanted to show my romantic side," William admitted.

And I think that was largely down to the Duchess of Cambridge, who made a point of speaking to Harry and when she did that, you can see them visibly relax… It's always been my understanding that behind the scenes, Kate has tried very hard to forge a rapprochement and act as a peacemaker between William and Harry."

January 2024: Kate's Surgery

In early 2024, Kensington Palace announced that the mother of three had been admitted to The London Clinic for a "planned abdominal surgery."

William was spotted visiting his wife at the hospital amid her stay. 

Coincidentally, William's father, King Charles III, also underwent a procedure for an enlarged prostate at the same facility and later announced that he had been diagnosed with cancer and would be temporarily stepping back from his royal duties while undergoing treatment. 

February-March 2024: Royal Speculation

As time passed without a single sighting of the princess, online rumors began circulating. This only intensified after the couple released a portrait on British Mother's Day of Kate and their three children, supposedly taken by Prince William. But several news outlets, including the Associated Press, took the image down, claiming it was manipulated. Quickly, conspiracy theories began popping up online regarding Kate's health and the state of the couple's marriage. 

March 2024: Kate's Cancer Reveal

Amid a whirlwind of speculation online and around the globe, Kate set the record straight with a heartfelt video message, revealing that she had been diagnosed with cancer. Calling the diagnosis a "huge shock," Kate revealed that she and William had chosen to wait to share the news with their three children, which led to the months of keeping the news private. 

"As I have said to [my children]; I am well and getting stronger every day by focusing on the things that will help me heal; in my mind, body and spirits," Kate said in her message. 

The proud wife added of her husband's support, "Having William by my side is a great source of comfort and reassurance too. As is the love, support and kindness that has been shown by so many of you. It means much to us both."

Following the announcement, ET's royal expert, Katie Nicholl, opened up about how the couple was weathering the storm. 

"We're told by the palace that Kate's feeling optimistic and that she's in good spirits," Nicholl shared. "Hopefully the same can be said of Prince William, but clearly he's going to be desperately worried. This is his wife, his partner of some 20 years. The mother of his gorgeous three young children."

Due to both his wife and his father, King Charles III's, cancer diagnoses, William is being forced to step up in his royal duties.

For the special occasion, Middleton opted for a white dress reportedly by one of her go-to British designers, Jenny Packham.
