Jamie Lee Curtis has announced that her older sister, Kelly Curtis, has died aged 69. The Freaky Friday alum, 67, posted an emotional tribute Saturday on Instagram, alongside a black and white photo of her sister. Kelly’s cause of death has not been shared. “A warm aloha to my older sister, Kelly Lee Curtis. She passed away this morning. In her home. In nature. At peace,” she wrote. “She was my first friend and lifelong confidant. She was jaw droppingly beautiful, and a talented actress. She played a mean game of hearts, collected turtles, loved her family, nature, music, thrifting, travel, Facebook, and Pokémon Go. She was proud of her Danish roots and Hungarian Jewish ancestry and was a devoted American patriot.“She will be remembered for her loving generosity, fierce opinions, endless curiosity, unique style, and her powdered, almond, crescent cookies at Christmas, hence her name, Auntie Cookie.”Jamie continued: “Kelly always signed off any message or fare thee well with a Hungarian blessing… Isten Veled, God is with you. Isten Veled to my sister of the sun and the moon, my Tai. I'll see you on down the line.”Jamie Lee Curtis called her sister ‘jaw droppingly beautiful’ in an emotional Instagram tribute (Getty Images)Kelly was the eldest daughter of late Hollywood icons, Tony Curtis and Janet Leigh, followed by Jamie.
