Kourtney Kardashian is putting an end to a paternity lawsuit brought on by male model Michael Girgenti, who claims that he is the father of her son, Mason.

Last week, Girgenti filed paperwork at a Los Angeles County Superior Court in a bid to get joint custody of the three-year-old child alleging he had unprotected sex with the reality TV star nine months before Mason's birth.

The model claims in the lawsuit that the alleged relationship between Kourtney and him heated up after they met at a photo shoot in 2008, and continued with months of texting in which she told him her relationship with Scott Disick was "on the outs" and "she wanted to hang."

Michael is hoping to convince Kourtney and her family that he is a "spitting image" of the now three-year-old boy, whom Kourtney shares with Scott.

Kourtney and Scott agreed to do a paternity test, and the results proved the allegations by the male model were false and Scott is in fact Mason's father.

"After three-and-a-half years of rumors and 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," said Kourtney in a statement.

According to the "Keeping Up With The Kardashians" star's attorney, Todd Wilson, Girgenti has been trying to get money from the media for years by selling the fake story. "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."

"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," Wilson added. "His claims are absurd and this is simply another shameful attempt to gain publicity and profit from fictional stories about my client."

Yet, Michael seems pretty sure Mason is his, despite the paternity test results, as he's still pushing his paternity lawsuit against Kourtney Kardashian, demanding a court-ordered DNA test under the pretense that the released results may have been fabricated. If Girgenti's paternity lawsuit still stands, he will ask a judge to grant him joint custody of Mason in the event that the new test shows he's the real father.

"We don't trust the results and believe it could have been fixed," his spokesperson said. "Still going to court to fight for court ordered results."
