Don't be shocked if another Tupac sex tape pops up because the rapper who co-starred in the first one, says he and 'Pac used to hang out like that "all the time."

Money B from Digitial Underground told a camera guy in Hollywood, he knew the tape — shot 20 years ago — would eventually see the light of day  saying, "I didn't know who had it, but I knew it was out there, so, I'm not surprised."

As first reported — the tape shows Tupac putting his arm around his homie Money B, while Tupac is getting, oral attention from a woman.
