Naomi Osaka responds to $450,000,000-worth Hollywood star after he says he helped her train for Australian Open success

Naomi Osaka responded to iconic Hollywood actor and comedian Kevin Hart after he hilariously took credit for the Japanese's ongoing run at the 2025 Australian Open. Osaka has won her first and second round matches at the hardcourt Major, and was particularly impressive in her second-round win over Karolina Muchova. The Japanese lost the first set but remarkably came back to win the match 1-6, 6-1, 6-3.

In the aftermath of her victory against Muchova, Osaka shared a combination of photos and videos from her successful second-round outing via an Instagram post, which she captioned:

"It’s sunflower season 🌻"

Kevin Hart, whose net worth is estimated to be at $450 million (as per Celebrity Net Worth), later commented on Naomi Osaka's post, writing:

"💪🏾💪🏾💪🏾💪🏾💪🏾💪🏾💪🏾 We trained for these moments 😂😂😂 Congrats"

The former World No. 1 and four-time Major winner soon responded to Hart.

"@kevinhart4real You counting the pickleball as training is taking me out 😭😭😭," Osaka replied.

"Word on the street is that I might be a pro in pickle ball …. Ok not really but I’m good damn it…. At least I thought I was until @naomiosaka came over to my house and whooped my ass like I stole something 😂😂😂😂😂," Hart wrote.

"First game I held my own 11-7 and felt good about myself…. The next game she made me understand the true definition of a pro and beat me 11-1 …. I got her right where I want her…. This isn’t over damn it!!!!!! Thank you for coming and being so damn cool and super thank you for being so sweet to my kids!!!!!
