Katie Boulter reached a career-high ranking of world No. 27 in the WTA rankings on March 4, 2024. She is also the current British No. 1 tennis player on the women's side.

Boulter's rise in the rankings has been impressive. She was ranked No. 151 in March 2023 and for many years relied on wildcards from the LTA in the UK to get into major events and boost her ranking.

However, her hard work and dedication, along with the support of her coach Biljana Veselinovic has propelled her into the top 30.

As Boulter continues her ascent in the rankings, many are excited to see what the future holds for this talented British player.

In July 2024, Boulter was seeded in the singles at Wimbledon for the first time in her career. She defeated Tatjana Maria in two sets. But in the second round, she lost to fellow Briton Harriet Dart.

Boulter's journey is an inspiration to aspiring tennis players everywhere, demonstrating the power of perseverance and hard work.

The exact timeline of De Minaur and Boulter's relationship is unclear, but Boulter confirmed in March 2021 that they had been together for a year.

The couple made their relationship "Instagram official" with an anniversary post from Boulter, and since then, they have frequently been seen together at tournaments, supporting each other and often sharing their affection on social media.

In December 2023, Boulter posted adorable pictures of their Christmas together.

The couple reportedly live together in Wimbledon, with Boulter finding that being closer to home and near where the action takes place helps her preparation.

2024.

De Minaur and Boulter seem to spur each other towards success, with both achieving major career milestones in 2024.

De Minaur broke into the top 10 of the ATP Rankings for the first time by defending his title at the ATP 500 Mexican Open in Acapulco, while Boulter secured the biggest title of her career at the WTA 500 San Diego Open.

Their victories happened just a day apart, with De Minaur flying from Acapulco to San Diego to support Boulter in her final.

Following De Minaur's win against James Duckworth in his first round at Wimbledon, the tennis star dashed to Boulter's player's box to support her as she took on German Tatjana Maria.

And now, they are headed for the aisle!
