Sharing a black and white picture of her ‘Papa’, the singer asked her 23.6million followers to pray for her great-grandmother after he passed away aged 88.

Alongside a picture of her beloved relative and her puppy Buddy, who passed away in July after an accident, she wrote on Instagram: ‘My two favourite Buddy’s are now playing in Heaven.

‘My heart is absolutely broken and I can’t even begin to imagine a world without my Papa but I know one day we’ll meet again and that’s what keeps me going. 

‘I hate writing this… But RIP Papa… I miss you so much already. I love you. Please keep my Mimaw in your prayers [sic].’
