It must be love because it’s on Instagram: Alex de Minaur and Katie Boulter are an item!

Aussie de Minaur posted an image on IG paying tribute to his new flame on International Women’s Day yesterday, a post that got plenty of reaction from fellow players.

“Happy international women’s day!! Specially to this one, I don’t mind you,” de Minaur wrote.

Brit Boulter commented “Guess you’re OK too” with a love heart and kissing emoji.

Then fellow Brit Laura Robson wrote: “Insta official here we goooo” and Freya Christie added: “Finally!!!! I’m so happy to see this post bless my timeline.”

De Minaur was the centre of much speculation during the Australian Open that he was in a relationship.
