Megan Thee Stallion and Klay Thompson stans can relax ... the two clearly didn't break up -- because Megan shared a clip that showed her getting down on her man!
The rapper posted the short vid to TikTok Friday night ... which begins with MTS begging Klay to put on a camo outfit while he declines. In the next shot, Klay caves ... and, he's feeling great about it -- dancing through a massive walk-in closet with the threads on while Michael Jackson's hit "You Rock My World" plays over it.
