Male Model Who Claims He Bedded Kourtney Kardashian Nine Months Before Son's Birth Caught In A Lie!

The male model, who claims  he could be the father of Kourtney Kardashian's son, Mason, has been caught in a whopping lie, RadarOnline.com can exclusively reveal.

In a bombshell interview with the new issue of In Touch Weekly, Michael Girgenti claims he had sex with the Keeping Up With The Kardashians star in April 2008, following a photo shoot for 944 magazine — and that after, "Kourtney left, and he never heard from her again."

Nine months later, on December 14, 2009, the now mother-of-two gave birth to Mason, purportedly the first child of her and beau, Scott Disick.

However, the model from Chicago, Illinois, fumbled his facts – or perhaps his fiction? - because in January 2010, one month after he made the exact same paternity claims to Star magazine, he told them in a follow-up interview that  he got an e-mail from Kourtney after their alleged steamy tryst, saying, "Last night was so much fun. But Scott's bugging me again, and I don't know what to do."

Does the glaring misnomer mean that Michael, now 26, is making up the whole story about Mason possibly being his son?

Star first broke the story of the Italian-Greek hunk's belief that he is the baby daddy in December 2009, and he now insists that he is speaking out once again in the hope that it will "finally push the Kardashians into taking a DNA test," he told In Touch.

"People say sometimes the best thing to do is forget about it, but it is not easy to do," said Girgenti, who believes Kourtney is "a good mother," but is skeptical of Disick's parenting skills and treatment of his longtime girlfriend.

Meanwhile, Kourtney has denied the model's accusations, and her attorney – calling Girgenti’s claims “preposterous and an outrageous lie” – said in a statement the two never exchanged contact information.
