The 70-year-old entertainer, whose real name is Mario Kreutzberger, had left Miami where he usually hosts the "Sabado Gigante" show on Univision to go to Chile to deal with the claims against him.
Lawyer Santiago Montenegro said that a DNA test indicates Kreutzberger is not the father of Patricio Flores Mundaca. But the attorney, who represents the plaintiff's siblings, says he may seek more DNA tests.
A prosecutor, meanwhile, is investigating an allegation that someone tried to bribe a lab worker to alter the DNA results on the TV host's behalf. Kreutzberger says he had nothing to do with any such attempt.
Univision spokeswoman Monica Talan said a new episode of his show is being taped this Saturday.
