Nice try!

A new sex tape circulating featuring Blac Chyna is making the rounds on the Internet, but the former stripper swears it's not her!

"The woman in the grainy footage does have significant similarities to [Blac] but it is absolutely NOT her," a source told TMZ. Umm, the chick has the same tattoos, nipples, piercings, and voice... so yeah.

This comes just days after an XXX video of Rob Kardashian's ex hit Twitter, which showed her performing oral sex on ex-boyfriend Mechie. She also claims she wasn't the one to release it, and that she's having authorities investigate. It's pretty obvious to us that she figured the Kim K road to fame was a sure thing, but it's backfiring.

Trolls have been critiquing her moves, and some of their comments are pretty savage!
