Influencer Kate Hudson announced on Instagram on Monday that her daughter, two-year-old Eliza, died of cancer. Eliza's father, Chance Moore, documented the family's journey with childhood cancer on the TikTok account @heyeliza.

Hudson is an Ohio-based influencer with over 630,000 Instagram followers who frequently posted about her life with daughter Eliza and fiancé Chance Moore. On Monday, she shared that Eliza had died on Sunday, Father's Day.

"Eliza Adalynn Moore," Hudson wrote on Instagram. "My sweet baby girl. I don't know how we will go on without you. I know we promised you we would be brave, just like you. But we are broken. Even though we know you are no longer suffering or in pain or frustrated with what life had become."

According to Hudson's post, Eliza was born on August 10, 2018, making her close to three years old at the time of her death.

The description of a GoFundMe organized by Moore, which currently has over $78,000 in donations, says that Eliza was diagnosed with a form of cancer known as a rhabdoid tumor when she was 10 months old. Rhabdoid tumors are most commonly found in infants and toddlers and the rare cancer is diagnosed in 20 to 25 new cases annually in the US, according to the Dana-Farber Cancer Institute.

Moore documented Eliza's life on the TikTok account @heyeliza, which has 5.5 million followers. The first video on the account dates back to March 2019, and Moore frequently posted videos where he tried to make Eliza laugh, beginning with the phrase, "hey Eliza."

Hudson announced in June 2019 that Eliza had been diagnosed with cancer and Moore began to document Eliza's hospital visits and treatment on TikTok the same year.

On June 9, Hudson posted about having to start making decisions about Eliza's funeral. On June 12, she posted about learning that there Eliza's cancer had spread and that there were "thousands" of rhabdoid tumor seeds in her right lung, heart, and diaphragm.

She said she and her fiancé were informed that they likely only had between a few weeks to months left with Eliza.

"I want to believe I will wake up from this nightmare and you will be there holding our hands. Telling us it was just a bad dream," Hudson wrote on Instagram on June 20.

"All I can say is I miss my best friend more than anything," Moore wrote in an Instagram post on Tuesday.

Hudson and Moore did not immediately respond to Insider's request for comment.
