Kourtney Kardashian is on the defensive over claims Scott Disick is not the biological father of their 3-year-old son Mason.
Kourtney Kardashian, 33, has been asked to allow Mason to undergo a paternity test.
The request was made by male model Michael Girgenti, who claims he and Kourtney Kardashian slept together nine months before Mason was born, In Touch magazine has reported.
During that time in March 2009, Kourtney Kardashian and Scott Disick, 30, were apparently on a break.
A legal representative for Kourtney Kardashian has branded Michael Girgenti’s allegations “preposterous and an outrageous lie”.
The legal rep insisted the reality star, who also shares daughter Penelope, 9 months, with Scott Disick, never gave Michael Girgenti her contact details after they briefly met at a photo shoot and never came into contact with him again.
Michael Girgenti, 26, told In Touch magazine: “After [Mason] was born, and I saw photos of him, I began to wonder. I would definitely want to acknowledge Mason if he’s my kid – he deserves to know his real father.”
This is not the first time the extremely wealthy Kardashian family has been confronted by allegations of paternity.
Kourtney Kardashian’s younger sister Khloe, 28, has had to regularly deny rumors that their late father Robert Kardashian was not her biological father.
Their half-sister Kylie Jenner, 15, also recently hit back at reports that her father Bruce Jenner may not be her real father.
Last month Kylie Jenner shared her disgust in relation to the rumors with her fans on Twitter, writing: “Yes, my father is my father and no my parents aren’t getting a divorce.
“You guys can’t believe any of these magazines. It’s all bulls**t.
“And even though I don’t let these stories get to my head. Imagine you at 15 & someone telling you your father isn’t your father.
“EWWWW people disgust me. You’re all pathetic.
“Wait. But you’re ACTUALLY pathetic. Going after a 15-year-old and telling her father isn’t her father. Like WHAT? Are you insane?
“This makes me so mad. And I’m not taking the time to write all this because this hurts me. I’m writing this for the other teens my age.”
