That girl who filmed Justin Bieber sleeping in Brazil may not be a hooker … but she has been paid for sex — at least that’s what one porn site is claiming.

TMZ has learned HotMovies.com says they shot XXX video of the girl — Tati Neves — a few years ago … and they plan to release it this week to come up off her newly popular name.

We’ve seen the scene and it’s definitely your run of the mill porn … with a slight Brazilian influence — they’re banging on a soccer field.

For what it’s worth … our Bieber sources are adamant the singer never touched Tati.

After seeing the video he may change his mind.
