When it comes to sporting power couples, Alex De Minaur and Katie Boulter are some of the most famous in the world – at least in the professional tennis circuit.
Both are in the prime of their careers as they travel the world to compete in various Grand Slam events, and their shared love of the sport is only eclipsed by the devotion they have for each other.
But they have hit a difficult moment after Alex was sadly knocked out of the 2026 Australian Open on January 28.
However, every inch his cheerleader, Katie shared some kind words on Instagram following his loss.
Sharing a photo of her beau on her Instagram stories, Katie wrote, “Proud is not a strong enough word.”
Alex, 26, has shared his devastation over being knocked out of the Open after losing to Carlos Alcaraz, who is ranked first in the world.
“It hurts right now. Losing at home is never easy,” Alex shared in a poignant Instagram post on January 28.
However, Katie, 29, will no doubt remain firmly by his side, and Alex has often lauded her as his number one supporter.
From their very first meeting to their most recent romantic updates, scroll on to read all about Alex and Katie’s relationship.
When did Alex de Minaur and Katie Boulter start dating?
The tennis power couple have been dating since 2020, but first went public with their relationship in March 2022.
Since then they have been navigating the ebbs and flows of life on the international tennis circuit.
In an April 2024 video for Tennis TV, the lovebirds revealed that they kept their romance a secret in the early stages of the relationship.
Leicester-born Katie and Alex said that in order to keep their relationship hidden, they would have breakfast at separate tables.
“We would rock down to breakfast at different times,” Alex said. “[It was often] different times, like 10 minutes later.”
However, their profiles skyrocketed in early 2024 when they competed at the Australian Open.
Taking a break from training and competing, the couple were seen looking all loved up in Melbourne as they headed to a restaurant. Later they strolled arm in arm through the city streets.
“They looked like they were totally in love,” an onlooker told New Idea at the time.
What has Katie Boulter said about Alex de Minaur?
Katie has described her fiancé Alex as her “inspiration.”
“I think he’s really rubbed off on me in so many ways,” Katie has previously told the Daily Mail.
“The way he holds himself and the way he works.”
“I can’t walk down the street with him separately,” Katie also said. “I feel like I’m sharing him with everyone, which isn’t a bad thing.”
During the 2025 Wimbledon tournament, Katie said she was thankful to have him as a supporter.
“I think think he has the best warmest heart. I’m so lucky to have someone like him by my side,” she gushed. “He’s so supportive and he also gives me an opportunity to be him at tennis… he is incredible. I could go on for a long time.”
Their love was firmly on show when Katie took to Instagram to post about her unexpected second-round win at the Australian Open in 2025. Alex quipped in response: “Is that you smiling,” which generated over a hundred likes.
Meanwhile, Alex has gushed over his affections for Katie, citing her as his number one supporter.
“I mean, I’m the lucky one. Even though I give her a little bit of stick here and there, I’m extremely lucky to have her,” he told reporters at the US Open.
“We’ve got each other, we have each other’s back. It’s amazing to have – I don’t want to sound too cliché – but a soul mate, so I’m happy to keep it going and yeah, happy wife, happy life.”
Are Alex de Minaur and Katie Boulter engaged?
The sporting power couple stunned fans with the news that they had been engaged for some time in late 2024.
The glamour couple took to social media on December 23rd that year, sharing a smiley selfie they had taken at an unspecified time, Katie’s dazzling engagement ring on full display.
“We’ve been keeping a small secret…🤭” they captioned the photo.
While a date for the wedding hasn’t yet been set, at the 2025 Australian Open, Alex joked that he needed to focus on “more wins” meaning “more money” and therefore “more wedding budget” in a post-match interview.
“When I’m out there on court and you see me so stressed out, I’m just thinking of the wedding budget,” he laughed.
“That’s why I’m like ‘I need to win more money, I need to win more matches.'”
When are Alex de Minaur and Katie Boulter getting married?
Just days ahead of the 2026 Australian Open, Katie revealed that they are planning to get married later this year.
“I’ve not been a massive dreamer about my wedding,” Katie told The Telegraph. “As long as my family are there, I’ll be happy.”
“I did sort of dream about a destination wedding,” she added. “Having a place you can go back to that’s your place. So it’s possible it’ll be in the middle of nowhere.”
Katie has hinted that their wedding might be in Europe, rather than the UK or Australia, their respective home countries.
In July 2025, Katie shared an array of photographs with Alex from what appeared to be a wedding venue, alongside the caption, “2026,” with a shush emoji.
The cryptic post led fans to believe that they were planning for their wedding, so it is likely that they might be saying “I do” in July 2026.
