To clear his name, the celebrity could take a paternity test to prove that he is not the father of the little girl.
He can do this at the Health Sciences Authority (HSA), or at paternity testing company, Paternity Testing Corporation Singapore, among others.
In the past year, about 110 people have visited the latter to take such tests, said its spokesman.
Mr Zane Lam told The New Paper: "Our main business is DNA paternity testing. We have been around for more than a year.
"Two to three people come to us for paternity tests every week or so.
"Clients are usually men who suspect that their partner's children are not theirs.
"A small number of women also visit us and they just want to know if their husband is the father of their children."
Mr Lam said that the company uses cheek swabs as samples.
"Of course we use other samples like fingernails and toenails, toothbrushes, drinking straws and cigarette butts."
Mr Lam said that, generally, it takes less than 10 working days to get results.
"However,an extra fee can be paid to expedite them. It costs customers at least $588 to do paternity testing."
A HSA spokesman said paternity testing there costs $925.
Said its spokesman: "The test covers DNA testing of three blood samples - from the father in question, the child and his or her mother."
The test can also be conducted with two blood samples, one from either the father or mother and another from the child.
The spokesman added: "Test results will be ready in four weeks."
