MediaTakeOut.com learned that a Britney Spears SEXTAPE just leaked - and it's VERY GRAPHIC.
The video, which MediaTakeOut.com VIEWED, but we do not have nor has ever possessed - shows Britney "riding" her man - who is filming the whole thing.
In the video, the 35-year-old mother of two is smoking what appears to be a JOINT while she's riding the "D" too.
Brit was putting in WORK too. We ain't seen hips move that well . . . since SHAKIRA!!!
We're not gonna post a link to the vid here (We don't want that SMOKE). But it's out there - and maybe someone in the comments below will post it.
