“Haven’t Met You Yet” singer Michael Bublé shocked fans when he announced his 3-year-old son, Noah, has cancer— but it’s not leukemia. It was widely suspected the child was suffering from the blood disorder, but sister-in-law Daniela Lopilato confirmed otherwise.

“To tell you the truth, I’m devastated. This is very recent,” Daniela reportedly texted to Argentinian journalist Tomas Dente Saturday. “The only thing I ask is that you don’t speculate because not everyone has children and can understand what this means.” She added: “Michael and my sister will publish more statements and I can't say anymore but it's not leukemia or the central nervous system a people are saying. That's all I can say.”

There are many types of leukemia. Some are more common for children. “Leukemia usually involves the white blood cells,” the Mayo Clinic writes. “Your white blood cells are potent infection fighters — they normally grow and divide in an orderly way, as your body needs them. But in people with leukemia, the bone marrow produces abnormal white blood cells, which don't function properly.”

Bublé’s sister, Brandee Bublé, Instagramed an inspiring message Friday, the same day the singer confirmed his son’s diagnosis on wife Luisana Lopilato’s Facebook page. “And now three remain: Faith, Hope and Love. But the greatest of these is love.”

Neither Bublé nor Lopilato have issued a statement since they shared Noah’s diagnosis.  “Luisana and I have put our careers on hold in order to devote all our time and attention to helping Noah get well,” Bublé, 41, wrote Friday. “At this difficult time, we ask only for your prayers and respect for our privacy. We have a long journey in front of us and hope that with the support of family, friends and fans around the world, we will win this battle, God willing.”

Bublé and Lopilato are also parents to 10-month-old son, Elias.
