"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. 

Roberts had celebrated her 99th birthday on August 16 per People, which was her goal, according to Watts.

"She lived 3 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!' 😂

"Here are a few pics of the wonderful family she created. Four generations in one pic!! Grannies are the greatest. May her stories and memories live on.🕊️💔♥️," the post concluded. 

Her brother, photographer Ben Watts, also wrote a tribute to his late grandmother: "Goodbye, Nanna. Rest easy. You taught Naomi and I so much when we lived with you: to save and reuse things, don't be wasteful and charity starts at home."
