Naomi Watts' grandmother has died aged 101

The 'King Kong' star shared a picture of her paternal grandmother holding up her letter from the monarch in a post on Instagram and wrote: "Our Granny Watts made it to 101 and a half.

"She got her letter from the King to celebrate her century, last night she rested in peace. RIP."

The tragedy comes just months after the death of Naomi's maternal grandmother Nikki Roberts, who passed away in August aged 99 three weeks after suffering a stroke.

After the loss, Naomi wrote in a post on Instagram: "My darling Nanna has left this world but her spirit will never leave us ...

"I'm truly blessed to have had the most wonderful relationship with her. She is such a huge part of who I am: her core values, her work ethic, and her mischievous humour and joy of life.

"My mum and aunts are all in pieces today, but we know what a great life she had. She just kept cracking on because she loved her life and her family.

"She lived three more weeks after a massive stroke because, in full beast mode, she showed us that when she was finally ready to 'peg it - she'd peg it'.

"She had one more goal to meet. Her 99th birthday!! One more party. One more family gathering.

"'I'll never forget her wicked laugh, her feisty spirit, her no-nonsense attitude, her no waste policy. She'd be trimming the mould off the bread and cheese: 'You don't need an expiration date - that's what a nose is for!' May her stories and memories live on."
