American rapper Megan Thee Stallion has announced the end of her relationship with Dallas Mavericks guard, Klay Thompson, publicly accusing the NBA star of infidelity in a candid Instagram post that set the internet ablaze on Saturday, April 25.

The 31-year-old Grammy-winning artist did not hold back in her Instagram Stories, directing her frustration squarely at Thompson. “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’???? I need a REAL break after this one,” she wrote, before following up with a formal statement confirming the split.

“I’ve made the decision to end my relationship with Klay. Trust, fidelity and respect are non-negotiable for me in a relationship, and when those values are compromised, there’s no real path forward. I’m taking this time to prioritize myself and move ahead with peace and clarity,” she said in a statement.

The couple had soft-launched their relationship in July 2025, and the romance quickly became one of the most high-profile pairings in celebrity culture. Megan was courtside at the start of the NBA season, seated beside Thompson’s mother, and the two appeared to be building a serious domestic life together — cooking meals for his parents, working out jointly, and spending Thanksgiving with his family. Earlier this year, Megan was captured on video during the 2026 Olympic Games in Milan congratulating engaged Team USA athletes, quipping that she too was “manifesting my engagement.” That engagement will now not happen.

Thompson’s season with the Mavericks had been a difficult one, with the team finishing 12th in the Western Conference with 26 wins and 56 losses and missing the playoffs entirely. During the campaign, he faced criticism that his relationship was affecting his performance on the court, though he publicly defended Megan against those claims.

Hours after the bombshell post went public, Thompson took to Instagram Live though not to fire back directly at the cheating accusations. In his live session, Thompson kept his tone measured, saying life had been good, and declining to engage with the specifics of Megan’s allegations. A viral tweet claiming he had accused Megan of cheating first and boasted about spending millions on her was later debunked as fabricated.

The breakup drew widespread reaction across social media, with NBA fans and the music world alike weighing in. “Just found out that Klay Thompson cheated on Megan Thee Stallion how does one cheat on Megan Thee Stallion?” one user wrote on X, capturing the disbelief that swept the internet. Others drew parallels to Thompson’s broader career narrative, pointing out that the NBA veteran had already left the Golden State Warriors in controversial fashion before the latest off-court drama.
