It seems the paternity scandal involving Kourtney Kardashian and model Michael Girgenti is getting to be too much for Kardashian’s longtime boyfriend Scott Disick. Kardashian headed to court Monday, as she continues to face a legal battle after Girgenti filed a paternity lawsuit in Los Angeles, claiming he is the father of her first child, Mason.

Disick has reportedly been living apart from Kardashian and is staying at a five-star hotel near Rodeo Drive. He has also been seen with a brunette who appeared to be in her 20s. During one occasion, “She was pulling a small suitcase on wheels and Scott put both of his arms around the small of her back kissed her on the cheek and whispered into her ear,” onlooker Thomas Johnson tells Life & Style. “The way he touched her, the way they looked at each other suggested they were a lot more than friends.”

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

“I just want the truth to come out,” he told InTouch as he readied for the 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 that Disick is Mason's father, 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.”
