Thompson and the rapper confirmed their relationship last summer. Commenting on the breakup, TMZ quipped: "Klay just fouled out of this one!"

However, the story didn't end there. Thompson fired back online, first stating on Instagram that he never cheated on Megan.

Subsequently, he went live and confirmed the rumors, alleging that Megan Thee Stallion cheated on him with one of his own teammates. He said he was "not shocked," called the teammate "a L," and announced he would never get into another relationship again.

Since joining the Dallas Mavericks, the legendary NBA sharpshooter has been plagued by injuries and inconsistent form.
