Word on the curb is that a sex tape featuring legendary rapper Tupac Shakur has surfaced.

It was reportedly filmed back in the early 90’s during Pac’s Digital Underground days and apparently at least one of his fellow D.U. bandmates was involved in the taping.

Shocked?

Neither am I, but in case you’re curious…

TMZ is claiming they have previewed a copy of a five-minute sex tape showing Tupac receiving oral sex while rapping and dancing (and I’m wondering… what took so long?)

The tape, shot in 1991, begins with a bunch of groupies in a living room during a house party. Tupac walks into the room with his pants down to his ankles, his shirt off … sporting several chains.

Tupac — whose head is shaved — pulls one of the women toward him, and she begins performing oral sex. As she does her thing, an unreleased song of Tupac’s is playing in the background, as Tupac is singing along and dancing, wiggling his hips.

And it gets even better.? As the woman services Tupac, who is holding a cocktail in one hand and a blunt in another, Money B from Digital Underground walks over to him.

Tupac puts his cocktail arm around Money B, continues singing and dancing … and the woman never stops.

As the tape ends it appears he’s ready to begin sexual intercourse. It’s unclear if there’s another tape.

We’ve learned the person in possession of the tape is making plans to release it.

I think I’d watch just to see what Pac was workin with… but that’s just me.

[Sidebar: I’d also want to scope it out to see if Jada Pinkett-Smith and/or Faith Evans were involved in any of the video taped festivities.]

Would you watch Tupac “perform” on sex tape?
