Coco Gauff followed up her U.S. Open semifinal victory Thursday by showing love to Naomi Osaka as she sat in the crowd.

During an on-court interview , the Florida native joyfully waved to Osaka, who was watching from the presidents box at Arthur Ashe Stadium in New York City. Gauff had just defeated the Czech Republics Karolna Muchov 6-4, 7-5.

I did not notice she was sitting here until now, Gauff told the interviewer before addressing Osaka directly.

Thanks for coming. I mean, Naomi, I remember the moment we had on this court I dont even remember like, three years ago. And it meant a lot to me, she said. Im so excited to have you back on tour and hopefully I get to meet your daughter. ... Thank you so much for coming, and hi to your mom, too.
