On Saturday, the rapper took to Instagram with a pointed message that accused the NBA star of cheating on her — and she didn't hold back.

Megan was first linked to the Dallas Mavericks player in July 2025, when they were seen on vacation together. From there, things seemed to move quickly. By October, the pair hinted that they were moving in together, and Megan even spent Thanksgiving cooking for Klay and his family.

Which makes her latest post all the more shocking.
In a statement shared on her Instagram Story, Megan wrote, "Cheating , had me around your whole family playing house...got 'cold feet' Holding you down through all your HORRIBLE mood swings and treatment towards me during your basketball season now you don't know if you can be 'monogamous' ????"

She followed up with another message that made it clear that she's done. "Bitch I need a REAL break after this one. Bye yall."
Naturally, fans were quick to react — especially given how serious she and Klay appeared to be. "I hate this for her," one Reddit user wrote. Another agreed they were "so sad" for Megan.
"No one deserves to be cheated on," one more added. "She looked so happy during that relationship 🥺"
As of writing, Klay hasn't publicly responded to Megan's claims, but BuzzFeed has contacted his reps for comment. We'll let you know if we hear back.
