Klay Thompson Cheated on Megan Thee Stallion With an Ex-Fling Since December: Report

The personal life of NBA star Klay Thompson is under scrutiny following reports that his relationship with Megan Thee Stallion ended due to long-term alleged infidelity. While the public only recently learned of the split, new claims suggest that the alleged infidelity began months before the couple officially parted ways.

A new report claims that the NBA star had been cheating on the 'WAP' singer since December. The timeline of the alleged affair has shifted the narrative surrounding their high-profile romance.

Blind Items Claim Long-Term Infidelity Since December

Recent reports from the TikTok account celebritea.blinds suggest that Thompson had been unfaithful to the rapper since late 2025. According to the account, Thompson was 'hooking up with a former fling and Megan had no idea.' The account did not name a source for its claims.

The account pointed to a series of blind items that allegedly predicted the relationship's demise well in advance of the public announcement.

One specific blind item from December 2025 detailed an incident where the basketball player was late to meet his girlfriend. The report claimed that 'the NBA star's excuse for showing up late to grab his singer girlfriend was because he was tied up handling a past fling she had no clue about.'

A subsequent blind item in January 2026 alleged that the 'NBA player is reportedly stepping out on the triple name singer and rapper' whenever he has the opportunity. And it was allegedly referring to the now exes, Megan and Thompson.

The TikToker concluded that 'the blind items were clearly correct this time,' noting that it predicted the breakup 'months in advance' due to Thompson's alleged infidelity.
