Alex de Minaur and his girlfriend, British tennis player Katie Boulter, celebrated their three-year anniversary in style with a romantic date night.

de Minaur and Boulter have been dating since March 2020 and frequently share glimpses of their relationship on social media. On February 18, Boulter wished the “handsome” Australian a happy birthday and shared some pictures of the pair enjoying each other’s company.

“Older but no wise. Happy birthday guapo (handsome),” Boulter wrote.

Alex de Minaur celebrated the occasion by sharing a picture of Boulter on their night out.

“Happy 3 years,” he posted with a heart emoji.

Boulter also documented the occasion and shared a picture of the Australian smiling against the backdrop of well-decorated tree.

“Date night. Happy 3 years,” she wrote.

Katie Boulter celebrates Alex de Minaur’s Mexican Open title win

Alex de Minaur won the biggest title of his career at the 2023 Mexican Open in Acapulco. He defeated Tommy Paul in the final on March 5 to pick up the seventh ATP title of his career.

His girlfriend and fellow tennis player Katie Boulter shared a heartfelt message for the World No. 18 following his triumph. She also joked that she would like to see him get a haircut next.

“Some people just deserve it all. Some people is this guy @alexdeminaur,” Katie Boulter wrote on Instagram.

“Next stop > a haircut,” she added.

Following his 3-6, 6-4, 6-1 win over Tommy Paul, the Australian expressed his happiness at seeing his hard work translate into success in Acapulco.

“It feels great, it feels amazing,” de Minaur said. “I know the hard work that’s put in to be here and it’s good to see the results.

He added that going into the Indian Wells and Miami Masters with a title win under his belt would give him more confidence and momentum at the ATP 1000 tournaments.

“It’s not always that you win the tournament and you get to finish a week unbeaten, so I’ll definitely cherish this going into Indian Wells and Miami,” he added.

Unfortunately, Alex de Minaur was unable to replicate his success at the BNP Paribas Open in Indian Wells as he lost his opening match to Marton Fucsovics in straight sets. The Australian will be hoping to make a better showing at the Miami Open scheduled to begin on March 23.
