The Tupac Shakur sex tape is a real thing after-all!!!

If you had any doubts about the existence of a Tupac sex tape … then doubt no more because photographic evidence from the tape has surfaced on the web.

Check out the images below:

Though the photos do appear grainy, you can’t deny that facial profile in the first pic. This is most definitely THE ONE AND ONLY Tupac Shakur.

In related news, TMZ is reporting that two porn companies are battling each other to buy the rights to the tape, and the first bid is well into 6 figures!!!

Sources close to the person in possession of the tape tell us … neither company has actually laid eyes on the footage … but both sites are serious about acquiring the rights.

TMZ has confirmed … one of the potential buyers is a site called YouPorn.com — and YouPorn.com honcho Corey Price tells us the site has made an official offer to pay $150k for the tape.

According to sources, the person in possession of the tape believes the offer is “way too low” — and is willing to hold out for more money.

We’re told the seller has been in contact with a second, unidentified porn site, which has vowed to to beat the current offer — but only if it can screen the footage first.

As TMZ first reported, the footage was shot in 1991… and it features the late rapper receiving oral sex from a woman while rapping, drinking and smoking a blunt at a house party.
