Ex-NBA player Joe Smith is not a fan of his wife's latest business venture ... absolutely losing it after finding out she has an OnlyFans account.
Smith's partner of five years, Kisha Chavis -- a former adult actress who went by the name Yasmine Pendavis -- shared footage of his reaction to discovering her XXX subscription-based profile ... and he was PISSED.
"Just finding out you got an OnlyFans page all these years," Smith said in the clip ... adding she should have had a conversation with him before hopping on the platform.
