The heartbreaking news was shared by Jamie Lee Curtis in an emotional tribute on social media. Rather than focusing solely on Kelly’s Hollywood career, Jamie painted a deeply personal portrait of the woman who had been by her side since the beginning.

Jamie continued her tribute by describing the role Kelly played throughout her life.

Born in Santa Monica, California, in 1956, Kelly Curtis was surrounded by Hollywood from the moment she entered the world. As the daughter of two of cinema’s most recognizable stars, acting seemed almost inevitable. In fact, she made her screen debut as an infant in the 1958 epic The Vikings, which starred both of her famous parents.

Although Jamie Lee Curtis would eventually become one of the industry’s most recognizable faces, Kelly quietly built an impressive career of her own. She appeared in a variety of film and television projects over the years, earning respect for her versatility and dedication to her craft.

Many movie fans remember Kelly’s appearance alongside her younger sister in the 1983 comedy Trading Places. Her film credits also included Magic Sticks, The Devil’s Daughter, False Arrest, and Thanksgiving Day. On television, she appeared in popular series such as The Equalizer, Hunter, Silk Stalkings, Judging Amy, The Sentinel, and even Star Trek: Deep Space Nine.

Yet according to Jamie Lee, Kelly’s greatest accomplishments had little to do with cameras or movie sets.

In her tribute, Jamie described a woman who embraced life’s simple pleasures and cherished the people around her.

She also noted how proud Kelly was of her heritage, embracing both her Danish roots and Hungarian Jewish ancestry.

Friends and family knew Kelly for her unique personality, sharp opinions, endless curiosity, and remarkable generosity. Jamie affectionately revealed that her sister’s holiday baking skills had even earned her a special nickname.

One particularly touching detail Jamie shared involved Kelly’s favorite farewell phrase. Whenever she ended messages or conversations, she often signed off with the Hungarian blessing “Isten Veled,” which translates to “God is with you.”

As she said goodbye to her sister, Jamie used those same words.

Jamie also reflected on the complicated but enduring bond they shared as sisters. Like many siblings, they experienced rivalry during childhood, especially after their parents divorced. Their lives eventually took them in different directions, and for a time they lived apart.

Yet their connection never truly disappeared.

Their relationship strengthened once again when Kelly attended Jamie Lee’s wedding to actor Christopher Guest in 1984.

Over the years, Kelly became an important part of Jamie’s family life. She even worked alongside her sister behind the scenes on films including Freaky Friday, Christmas with the Kranks, and You Again.

In her later years, Kelly shifted her focus from acting to documentary filmmaking. She directed projects such as Marby Jets Are Go and Curling in Stanley, showcasing her curiosity about people, communities, and everyday life. Those who knew her say the move reflected her genuine interest in storytelling beyond Hollywood glamour.

At this time, no cause of death has been publicly announced.

For Jamie Lee Curtis, however, the loss extends far beyond headlines and film credits. It is the loss of a sister who shared her childhood, celebrated her milestones, and remained a constant presence throughout decades of life’s ups and downs.

As tributes continue to pour in, Jamie’s final words to her sister resonate with particular poignancy.

God is with you.

And for those who loved Kelly Curtis, it is a farewell filled with gratitude, affection, and the comforting hope that she truly found the peace her family believes she deserved.
