Who is Katie Boulter? Alex de Minaur's girlfriend
Boulter is a 27-year-old tennis player from England, with a career-high ranking of 50 achieved in September last year.
She first played Wimbledon qualifying in 2014 as a 17-year-old before reaching her first Grand Slam main draw at the All England Club in 2017.
In 2018, she won her first match at a major with victory against Veronica Cepede Royg at Wimbledon, before bowing out in the second round to Naomi Osaka.
Boulter has been on the rise in recent years, reaching the third round of her last three majors and winning a WTA title at the Canberra International in 2023.
At the United Cup 2024, Boulter earned the best win of her career as she downed world no.5 Jessica Pegula in three sets.
When did Boulter and De Minaur start their relationship?
Boulter and De Minaur's relationship became public news in March 2022.
With Boulter on the WTA tour and De Minaur on the ATP, tennis often takes the pair away from each other.
However, Boulter and De Minaur teamed up to play mixed doubles at Wimbledon 2023, winning their first match but losing their second.
The duo avoided playing each other in mixed doubles at the United Cup with Australia using a specialist doubles pairing.
However, there is a chance that both could make their Olympics debut at Paris 2024 and tussle it out for their respective nations in a contest.
