She revealed that she receives comments wishing death on her family, and one of the users also commented, 'hope you get cancer'. Highlighting the extreme level of hate, she said that it is an awful thing to do (as quoted by ESPN)."I just wonder who the person is that has sent that. I don't think it's something that I would ever say to my worst enemy. It's just an awful, awful thing to say to anyone. It's horrible. It shows how vulnerable we are. You really don't know if this person is on site. You really don't know if they're nearby or if they know where you live or anything like that," said Boulter.Following this, Alex de Minaur backed his fiancée by lauding her for taking a step against this and shining bright. Talking about how it happens to every single athlete, he said:"It's great for her to step up and shine a light into this, which is something that happens to every single tennis player out there. Every single athlete, I would say. Hopefully, there is something that can be done about it. It's something that's been going on for a while now. It's something that a lot of people have spoken out against, but it doesn't change."Alex de Minaur and Katie Boulter announced their engagement on December 23, 2024, by sharing a picture of themselves with the latter flaunting her engagement ring.
