Not cool!

Demi Lovato recently described a super-awkward encounter at her gynecologist's office, and it'll definitely make you cringe.

"There's been so many uncomfortable, and actually violating moments, where I've been to the gynecologist and the doctor's like, 'Can I have an autograph for my daughter?'" she recalls in a new interview with New Zealand radio station ZM. "I'm like, 'F--k you, what the hell is wrong with you?'"

And her embarrassing moments don't stop at doctor visits.

"Or I'll get like, a laser, and someone will be like, same thing ... "My such and such is a big fan,' and I'm just like, great, well you can now tell them that you've seen my vagina."

But at least the 22-year-old singer isn't afraid to stick up for herself -- on Thursday, she wrote a lengthy response to tattoo artist Ashley McMullen, who gave her a pink lips tattoo she recently covered up. Demi referred to it as a "vagina tattoo" on Instagram, and hashtagged, "#kidsdontdodrugs."

Obviously, McMullen wasn't happy with Demi's diss. "Thanks for getting the tattoo covered up I did for free that you specifically asked for," she wrote in a now-deleted Instagram. "Not to mention you didn't even have the courtesy to offer me any money in the first place. You pissed all over our toilet seat and you made a fool of yourself. What a shame that people look up to you."

Demi's response? Basically, "sorry not sorry."

"I apologize for making fun of your work.. But... if I were you, I wouldn't claim that one because it looked more like an open vagina (or even a butt hole as my 8 year old little sister called it at the time.)," she wrote. "I also wouldn't be admitting to the fact that you tattooed a very intoxicated 18 year old on a tour bus without the proper judgement that most legit tattoo artists have of saying 'Hmm... This underage kid is wasted, maybe I shouldn't permanently ink a hot pink kiss mark on this girl's wrist....? Oh well... F--k it, she's famous.'"
