Tupac Shakur's 1991 sex tape is officially off the market — the XXX footage has been sold to a private collector.

Sources connected to the deal say, the former tape owner decided not to sell to a big company out of principle — claiming the corporate porn companies were "parasites."

No word on what it sold for, but as previously reported, bids for the background music alone — an original, unreleased Tupac track — had reached $1,000,000.

A rep for the Tupac estate says, it plans to block any future sale of the tape and make sure the tape never sees the light of day.
