Michael Buble’s son doesn’t have leukemia, according to the child’s aunt, who said she wants the public to stop speculating about the boy’s illness.

Daniela Lopilato told an Argentinian TV- station that three-year-old Noah’s cancer diagnosis has left the family “broken in half,” the UK Express reported Saturday.

But she tried to stop rumors being spread about the specific type of cancer, writing to a reporter: “Michael and my sister will publish more statements and I can’t say anymore but it’s not leukemia or the central nervous system as people are saying. That’s all I can say.”

She added: “The only thing I ask is that you don’t speculate because not everyone has children and can understand what this means.”

Buble and his Argentinian-model wife Luisana Lopilato announced Friday that their son was diagnosed with cancer after he became ill with what they thought were the mumps.

“We are devastated by the recent diagnosis of cancer of our eldest son Noah who is currently receiving treatment in the United States. We’ve always talked about the importance of family and the love we have for our children,” they said on Facebook.

The couple, who also have a 10-month-old son Elias, declined to identify what kind of cancer Noah has, and said they are putting their careers on hold to get the child treatment.
