Megan Thee Stallion Calls Out Klay Thompson for Alleged Cheating in Public Breakup

Megan Thee Stallion has publicly ended her relationship with Dallas Mavericks star Klay Thompson, alleging infidelity in a candid Instagram Story . The Megan Thee Stallion and Klay Thompson breakup news broke on Saturday, April 25, sending shockwaves through both the music and sports worlds.

The three-time Grammy winner did not explicitly name Thompson, but her message left little doubt about who she was addressing. “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 wrote.

She concluded her statement with a definitive farewell: “Bitch I need a REAL break after this one. Bye yall”.

The couple, who went public in July 2025, had recently been the subject of intense speculation. Despite multiple fact-checks debunking previous viral cheating rumors in March 2026, the relationship appeared to be thriving just weeks ago. Thompson famously renamed his boat the “SS Stallion,” and Megan reportedly organized an elaborate “Klay Day” celebration for his birthday featuring a surprise performance by Bone Thugs-N-Harmony. Reports also suggested the couple had purchased a home together.

Megan had previously spoken highly of Thompson, telling PEOPLE that she had “never dated somebody so kind” and that he made her “genuinely happy”.

As of this writing, neither party has released an official statement beyond Megan’s Instagram Story. The Dallas Mavericks have not commented on the situation involving their star player. Fans are reacting strongly to the news, with many expressing support for the rapper’s decision to prioritize her well-being.

The public nature of this split and the specific allegations of infidelity and emotional volatility, suggests a complicated road ahead for both celebrities as they navigate life after their high-profile romance.
