The singing superstar speaks publicly about his beloved grandmother’s battle with dementia.

When she died two years ago, Michael Bublé behaved in exactly the way his Grandmother would have wanted; he went on stage and performed to thousands of fan who had bought tickets to his show in Mikwaukee, Wisconsin. Although visibly upset, he insisted that the show must go on. ‘I know she wouldn’t want me to cancel, ‘he told the audience. ‘She’d want me to come and do the show, smile and do what she supported me doing.’

However, it wasn’t until an interview last week on BBC Breakfast that the crooner opened up about the cause of his maternal grandmother’s death. ‘We lost her after a long battle with Alzheimer’s,’ he said, ‘which is tough for the person with it, but sometimes even tougher on the caretaker. Mom had a really tough time with it.’

Buble’s maternal gran Iolanda played a big part in the singer’s early life. ‘She raised me like a Mom,’ he recalled shortly after her death. Discussing the songs on his new album Nobody But Me, the 40-year-old singer also admitted that his version of The Very Thought of You, holds a very special place in his heart. ‘When I sang it the first time, I thought about my grandmother,’ he said, acknowledging how much he still misses her. ‘No matter how ready you think you are… there’s no preparation for never being able to tell someone you love so much that you love them again.’

Nobody but Me goes on sale 21 October.
