Rock's attorney, John Mayoue of Atlanta, said a Bulloch County judge sent results of the paternity test to lawyers on both sides of the case.
"The results of the test are that Chris Rock is not the father of this child," Mayoue said. "It is conclusive."
The mother, however, disputed the test results.
Kali Bowyer, who lives in Bulloch County, west of Savannah, tried in March to file a paternity lawsuit against Rock seeking child support and medical coverage for her son, Jordan. She withdrew the lawsuit after court officials told her it was outside the southeast Georgia county's jurisdiction because Rock is a New Jersey resident.
Rock and his wife, Malaak, said in a statement Monday they were happy to put the case to rest. They accused Bowyer of telling "multiple lies" to sell her story to tabloids.
"We also express our deepest prayers for the welfare of Ms. Bowyer's son who has continually been embarrassed and exposed in the media by his mother," Rock's statement said. "We have spent a tremendous sum to litigate this case and are asking our attorney to pursue all legal remedies against her. Additionally, we would like for any monies Ms. Bowyer has taken from the tabloid media based on this false story to be donated to Bulloch County, Ga., charities for the benefit of disadvantaged boys and girls."
Bowyer said Monday she had never received money for her story and she believed Rock had violated a confidentiality agreement by making the paternity test results public.
"I could've sworn we weren't supposed to talk about it until we were done with mediation," Bowyer said.
She said she planned to ask the judge to order another DNA test to challenge the results of the one that ruled out Rock as her child's father.
Bowyer, 35, said she met Rock at a Los Angeles nightclub when she was living in California 13 years ago.
She denied making any money from the case despite offers of thousands of dollars from television shows and tabloid magazines.
"I am sick and tired of being made out to be a liar and a fraud," she said.
Rock recently directed and starred in the film "I Think I Love My Wife," and is behind the hit television series "Everybody Hates Chris," which is based on his childhood. He and his wife have been married for 10 years and have two young children.
