Klay Thompson and Megan Thee Stallion Relationship Timeline
Klay Thompson and Megan Thee Stallion's relationship first became the talk of the town in early 2025 when the NBA star was spotted by fans in the background of Megan Thee Stallion's photos. Shortly afterwards, in July 2025, they confirmed the relationship.
On July 12, 2025, Klay posted Instagram photos of himself snuggling and holding hands with a woman whose curly hair and pink stiletto nails matched Megan’s recent vacation pics, quick‑firing fan speculation. In the next few days, Megan posted more images and Klay effectively “hard‑launched” them.
The couple made their official, red‑carpet debut at the Pete & Thomas Foundation Gala (Megan’s charity gala for her parents), just days after, in July 2025. Megan revealed that they met at a "meet-cute" and started dating.
Since then, everyone believed the couple to be strong, until weeks ago when reports claimed that they unfollowed each other on social media.
