Naomi Osaka hilariously calls out her sister with post-Australian Open win message

LOL what?!

I am a huge fan of the “writing a message on the glass in front of the camera” tradition after tennis matches (see what Jessica Pegula has done with them).

So I fully expected Naomi Osaka to say something to her fans after a straight-sets win over Serena Williams in the 2021 Australian Open semi-finals. But nope! She wrote this: “Mari stop sending [weird] images in the groupchat!”

That’s a message to her sister Mari, who I guess has been sending weird images in a groupchat with Naomi and others. That’s a pretty funny public callout right there!

Here’s the moment:

And here’s what appears to be Mari’s answer on Instagram (and WARNING: it’s weird!!!!)

GAHHHHH! I agree with Naomi.
