From MTO: just got word that a SEXTAPE is being sold - containing Nas babys motherCARMEN getting it poppin with a man who APPEARS TO BE JAY Z. This is NOT RUMOR - it's 100% FACTS!

A informant was given a SPECIAL PREVIEW of the tape on a cellphone. The tape, which was taken around the year 2000 shows Carmon and the man looking like Jay Z having RELATIONS. The insider explained, "You can see Carmen's face clearly .... i saw oral, both ways .... penis and vagina is clear."

We're working on getting screenshots of the tape. Stop by a little later today - we should have em by then!!
