X Factor judge Sharon Osborne, who has faced her own cancer battle, has led a wave of celebrity support for Michael Bublé who revealed his son had been diagnosed with the disease.
The devastated singer and his Argentinian wife posted on social media that their eldest son Noah, three, had been diagnosed with cancer and they would now be quitting all work for the foreseeable future to concentrate on his health.
Following the news, Mrs Osborne, 64, said she was thinking of the family.
She took to Twitter to say: “Sending positive thoughts and prayers to @MichaelBuble and Luisana and for their son Noah.”
Mrs Osborne famously fought cancer herself and it was documented on the reality show the family were appearing in at the time, The Osbornes.
A host of other stars made sure to show their support for Mr Bublé,41.
The shock diagnosis came just hours after Mr Bublé had been on a successful publicity tour, including performing on a special BBC show and on BBC Radio 4’s Desert Island Discs, in which he said how incredibly important his family were to him.
Mr Bublé said if he ever had to make a choice between his family and his performing career, his family would always come first. While he was speaking hypothetically at the time, he has now been forced to make that choice.
Other celebrities sending love and prayers to little Noah, included fellow singer Josh Groban, who wrote: ‘My family & I send all our love &prayers to @michaelbuble’s 3 year old son Noah as he fights cancer. Stay strong little guy.”
Meanwhile, young actress Joey King posted: ‘Praying for @michaelbuble’s son Noah. Cancer is a monster. You can do this Noah.’
And the singer received support from British celebrities too who had been moved by the plight of little Noah, like former boyband member Brian McFadden and lingerie firm Ultimo founder Michelle Mone.
Earlier in the day, heartbroken Mr Bublé and his wife Luisana, 29 wrote: “We are devastated by the recent diagnosis of cancer of our oldest son Noah, who is currently receiving treatment in the United States.We’ve always talked a lot about the importance of family and the love we have for our children.
