Kardashian, who was the subject of a 2007 sex tape, split from American football star and model Reggie Bush earlier this summer (09), and now Ortega claims she was romancing the New Orleans Saints running back while he was dating his ex - and she has the footage to prove it.
Speaking on New York radio station Hot 97, Ortega reveals, "Me and Reggie were friends that became more... during Kim... (but now) me and Reggie do not communicate... I don't want to.
Asked if sex tape rumours are true, Ortega said, "Possibly... There's stuff that I have. I have no idea what I'm gonna do with it, to be honest.
But the model dismissed reports she's expecting Bush's child: "I am not pregnant.".
