Kourtney Kardashian 'fuming' after model Michael Girgenti demands paternity test for Mason, claims he could be the the real father - NOT Scott Disick

Kourtney Kardashian has been left "raging" after claims that her three-year-old son's real biological father is model Michael Girgenti - NOT her boyfriend, Scott Disick.

The 33-year-old has been asked to allow Mason be given a paternity test to prove that the 26-year-old model is not his real father.

Michael Girgenti claims he slept with Kourtney nine months before Mason was born, when she and Scott were apparently on a break.

But Kourtney and Scott's lawyers have hit back at the reports, apparently labelling them "preposterous and an outrageous lie".

Michael 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."

He claims he met Kourtney on a photoshoot, had a one-night stand with her and says she never left him her contact details.

And although the Kardashian has kept quiet about the claims, her sister Khloe Kardashian took to Twitter to post a reflective statement.

She tweeted: "A strong woman takes the bricks the devil throws at her and uses them to lay a firm foundation and moves forward, stronger."

Khloe, 28, has previously had to deny rumours that Robert Kardashian was not her biological father, while their half-sister Kylie, 15, recently denied that Bruce Jenner is not her real father.

It's like Star Wars all over again.
