Megan Thee Stallion & Klay Thompson Dating, at Least for Summer '25

Megan Thee Stallion's taking advantage of Klay Thompson's summer off-season ... the NBA legend was cryptically spotted in her new IG post -- and it's because they're dating!!!

The "Hiss" rapper has a win-win situation with her social media posts doubling as promo for her Hot Girl Summer swimwear line ... but Klay's "Where's Waldo"-esque cameo in the background of her poolside shot was hard to ignore!!!

Meg knows her way around the hardwood ... she was linked with Chicago Bulls player Torrey Craig up until her Coachella performance in April -- but seems like all plays are running through Klay now.

We reached out to Meg's team ... no word back yet, but given her Houston hometown and Klay's current slot with the Dallas Mavericks, seeing each other shouldn't be an issue!!!
