Celina Powell is the game's proudest thot.

She's not afraid to shamelessly point her well-worn puss at folks like Tekashi 6ix9ine and Joyner Lucas, and notoriously tried to trick Offset into thinking he knocked her up.

But there's one rapper's D she wants nothing to do with -- and for good reason.

During a chat with Adam 22 of No Jumper, Powell explained why she won't be adding NBA YoungBoy to her body count.

"All the bitches line up for NBA YoungBoy and he admitted he had herpes so... I would never f*ck that little boy," Powell said. "He's so angry."

Later in the interview, she admitted to committing crimes, including hacking Tory Lanez and booking him for shows.  But we're sure her old friend 6ix9ine already told the Feds about all of that.
