Scott Disick and Kourtney Kardashian were seen leaving a Los Angeles hospital on Thursday after Scott underwent a DNA test to prove that he is indeed the father of Mason.

Kardashian was accused earlier this month of having a tryst with a male model, Michael Girgenti, the year before she became pregnant with Mason. Girgenti has claimed that he is Mason’s father because they had unprotected sex while Kourtney was on the outs with Scott. He requested a DNA test and said that if Mason was his child, he wanted partial custody.

“This individual has been selling false and fabricated stories to the tabloids for years about Kourtney Kardashian and her son, Mason. Scott Disick is Mason’s father,” Kardashian’s attorney, Todd Wilson, said. “We have not seen the reported court filing, but we are informed that this individual has been seeking to get paid to publish his ridiculous pleading. His claims are absurd and this is simply another shameful attempt to gain publicity and profit from fictional stories about my client.”

Kourtney confirmed on Thursday that Scott is Mason’s father and released a statement, saying, “After three-and-a-half years of lies being spread by an individual I met briefly at a photo shoot, I am setting the record straight that Scott is Mason’s father. While it saddens me to have to address these ridiculous lies – especially when the truth was never in doubt – this story must be put to rest.”

Girgenti, however, is reportedly pressing on with the paternity suit despite the results.

“We don’t trust the results and believe it could have been fixed,’ his spokesperson told Radar. ‘Still going to court to fight for court ordered results.”
