Kourtney Kardashian Paternity Scandal: Headed To Court After Model Michael Girgenti Claims To Be Mason's Father

Kourtney Kardashian is expected to head to court December 16, as she continues to face a legal battle after model Michael Girgenti filed a paternity lawsuit in Los Angeles, claiming he is the father of her first child, Mason.

Girgenti is reportedly seeking joint custody, after alleging he had sex with her in March 2009, nine months before the reality star had Mason.

“I just want the truth to come out,” he told InTouch as he readies for the Dec. 16 court date. “At this point I have nothing to say to her, but if I am the father, I need to be slowly integrated into Mason’s life before more time passes. If I’m not, I can rest at ease — and everyone can move on.”

In August, the Kardashian family released results of a paternity test stating Kourtney’s boyfriend Scott Disick is the father of Mason, but Girgenti believes the results were fabricated and wants to have a test taken at an independent facility.

Kardashian, 34, has denied the allegations, with her lawyer telling InTouch magazine back in March, "They did not exchange contact information. Since the Aug. 20, 2008, on-set photo shoot, Kourtney never spoke with him, saw him nor met him again. Kourtney has never been alone with him, and Kourtney certainly has never physically/intimately been with Mr. Girgenti.”

The Chicago native spoke with InTouch in March about their alleged sexual tryst. "We started kissing, making out and touching each other. My shirt was off. We were fooling around on the couch a little while before I took her to the bedroom.”

The 26-year-old model then says he and Kardashian undressed and were intimate and did not use protection, as he assumed she was taking birth control. She and her longtime boyfriend, Scott Disick, were on a break during this time, he says. Girgenti claims he tried to contact Kourtney after the March 2009 encounter, but he was continuously ignored.

The Kardashian sister gave birth to Mason Dec. 14, 2009. Kardashian and the Los Angeles-based model worked together in 2008 on a “944” magazine photo shoot. "I would definitely want to acknowledge Mason if he's my kid," Girgenti said, according to The Daily News. "He deserves to know his real father."
