Kourtney Kardashian`s alleged ex-fling Michael claims he could be her son`s real dad New York: Kourtney Kardashian`s alleged ex-fling, model Michael Girgenti, has claimed that he could be the real father of her 3-year-old son Mason Dash Disick and has demanded a DNA test.

The two worked together on a 944 Magazine photo shoot in 2008 and Girgenti told the Touch magazine in depth details of an alleged tryst he had with the reality star in March 2009, the New York Daily News reported.

The LA- based model also said that Kardahsian told him that she was on a break at that time from boyfriend, Scott Disick .

Kardashian got back together with Disick, who is publicly known as the father to Mason, who she gave birth to on December 14, 2009.

The reality star acknowledged working with the dair-haired model at the photoshoot but her lawyer said that the rest was completely false.

Her lawyer added that the 33-year-old star had never been alone with the model, and had never had any physical relationship with him.

He said that the claim that Girgenti could be Mason`s father was `preposterous and an outrageous lie.`
