Explicit video footage featuring late rapper Tupac Shakur allegedly receiving oral sex has surfaced 15 years after his death.

The sex tape reportedly features the hip-hop icon topless at a house party, dancing with his pants down as a female groupie pleasures him to the sounds of his own music.

According to TMZ.com, the video footage also appears to show Shakur's one-time Digital Underground group member Money B drinking and smoking marijuana with the star as the unidentified woman performs the sex act.

The footage, shot in 1991, is now expected to be made public - the person in possession of the tape is currently fielding offers for its sale.

Shakur was killed in a drive-by shooting in Las Vegas in 1996, aged 25.
