Remember that creepy chick who filmed Justin Bieber sleeping? Tatiana Neves Barbosa swears she's not a hooker, which may be true. But it's also true that she got paid to have sex at least once ... on camera.

Yup, Neves starred in a porno, because apparently someone would be willing to pay to see a 6 (in good lighting) get down and dirty on film.

TMZ reports that a porn outlet shot a XXX-rated video featuring Neves a few years ago, and they plan on releasing it this week now that her Google alerts are probably blowing up. We won't go into any filthy details, but apparently a soccer field is involved. Classy!

And despite her evident wealth of sexual experience, Neves swears Biebs was one of the best men she's ever had in bed.

“There was a lot of exchange of affection," she dished to AKM-GSI (via Page Six).
“He was the way a man has to be in bed.”

As for why she'd sell him out, Neves explained, “I didn’t want the video leaked but now there is not much I can do. I filmed like any fan would,” she said. “He is a star. He is beautiful.”

Interesting. Because, well, TMZ sources swear that Biebs never even touched her. And considering the steep downgrade it would be from his past conquests, we believe them.
