Three-year-old Noah has been undergoing treatment ever since he was diagnosed with liver cancer in November, the Sun reports.

The little boy has completed his first round of chemotherapy and reportedly has an operation planned for the end of December.

But, he has reportedly responded well to treatment and will get to spend the festivities with dad Michael, 41, mum Luisana, 29 and his little brother, eleven-month-old Elias.

The family usually spend Christmas in Michael’s hometown of Vancouver but this year they will be California at their Los Angeles home.

Luisana’s brother Dario and father Eduardo are flying in from Argentina and her mother Beatriz, who is already in LA with her model daughter.

According to the Mirror, an Argentinian new site said: “The youngster has successfully finished the first stage of his treatment.

“This is without doubt the best present for his parents and the relatives who have been helping them out since they learnt about his cancer diagnosis.”

“They’re all used to spending the festive season in Vancouver but this year they will be where Noah is.”

Last month, Michael and Luisana revealed the sad news that Noah had been diagnosed with cancer.

A statement from Bublé posted on both his and Luisana’s pages read: “We are devastated about the recent cancer diagnosis of our oldest son Noah who is currently undergoing treatment in the US.

“We have always been very vocal about the importance of family and the love we have for our children.

“Luisana and I have put our careers on hold in order to devote all our time and attention to helping Noah get well.

“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.”
