A DNA test reveals Scott Disick is Kourtney Kardashian's son Mason's father finally putting to rest the claims of male model Michael Girgenti.

Kourtney Kardashian was asked by Michael Girgenti to allow her three-year-old son to undergo a DNA test after the model claimed that he and Kardashian slept together in March of 2009 while she and long-time boyfriend Scott Disick were not together.

Lab results reveal however that Girgenti's claims of paternity are false. The 33-year-old reality star told E! News, "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 appear undeterred though and told the press that he will go ahead with the lawsuit he filed this month. He said he had "unprotected vaginal sex" with Kardashian in his apartment in Glendale in March of 2009.

'We don't trust the results and believe it could have been fixed,' Girgenti's spokesperson told Radar. 'Still going to court to fight for court ordered results," the spokesperson added. Girgenti told media that before he filed for a suit, he wrote a letter to Kardashian urging her to have Mason undergo a DNA test. Girgenti allegedly wrote, "My attentions [sic] are not to hurt the family you've created with Scott. Please take this final request for a DNA test seriously. Because if you don't, I will be forced to take legal action and sue." In the letter, the male model also assured Kourtney Kardashian that he will be a great father to her child.

Kardashian maintains that the allegations of Michael Girgenti are absurd. Todd Wilson told reporters, "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."
