"Bad Girls Club" star Natalie Nunn tells TMZ ... she's ready to and willing to raise a big legal stink to shut down a person trying to shop naked pics of the reality star to various media outlets.
That's right ... Natalie tells us the pics are legit ... but they were supposed to be private.
TMZ has learned ... the person shopping the photos is claiming to be a disgruntled ex-assistant who's more interested in embarrassing Natalie than scoring a huge payday.
We spoke with Nunn who tells us, "Those photos DO NOT belong to him and I will take legal action against anyone who releases them!"
"Honestly those images are mine and I just don't want to have to get my lawyers involved."
Bad girl trying to protect a good girl reputation? Weird.
