TikTok influencer Eva Evans has died. She was 29.

The "Club Rat" series creator's sister announced the shocking news via Instagram Sunday. A cause of death was not disclosed.

"Yesterday my family received news that our sweet, fabulous, creative, caring, hilarious Eva, my beautiful sister, has died," Lila Joy wrote alongside a photo of Evans smiling.

"After 24 hours, I still find myself in a constant cycle of denial and acceptance, so I know how unbelievable and hard to process this news will be," she added.

Lila went on to announce that the family will hold a celebration of life for Evans in Lower Manhattan on Tuesday evening.

She asked those interested in attending to send her a direct message to get more details about the event.

"I wish I had Eva here now to refer to because she would have better words and know how to say what I don't," Lila wrote. "I am keeping this brief, so we can plan for the next few days, but you'll be hearing a lot more from me on how much Eva means to me and just how different the world will be without her."

Peers, pals and fans sent their condolences and messages of support to Lila following the loss of her sister.

"I literally can't believe this," Julia Fox wrote in the comments section of Lila's tribute.

"This is heartbreaking. I'm so so so sorry sending you and your family all of my love and strength," model Lindsay Vrckovnik wrote.

Another comment read, "She was a sweet soul and from my few interactions with Eva know she was a bright light to anyone she was around."

"There was something so incredibly special about Eva. She's fire, creativity and love personified. My deepest condolences to you and your family. I'm so so sorry for your incredible loss," a fourth commenter said.

Evans directed, wrote, produced and starred in the five-episode series "Club Rat," which premiered on Prime Video last year.

In the series, Evans played an influencer named Eva who tries to get back into the New York City dating scene after a video of her humiliating breakup goes viral.

Evans' TikTok account had amassed more than 300,000 followers and nearly 14 million likes by the time of her passing.

She last posted on her account four days ago when she shared a video of her commenting on JoJo Siwa's recent edgy rebrand.

The comments section of the video was also filled with messages from people expressing shock over Evans' sudden death.

"I just saw someone post you were gone and thought about you earlier. I can't believe it!!" one TikTok user commented.

Fox also commented under the video: "I will miss you so much. I love you so much."

Some noted that Evans' passing came just days after the death of another TikTok star, Kyle Marisa Roth.

Last week, Roth's sister Lindsay announced via Instagram that her sibling, who was known for posting Hollywood blind items and gossip, died earlier this month. She was 36.

Roth's mom Jacquie confirmed the news to NBC News, saying in a statement: "Kyle truly loved so fiercely. She was a truth seeker. A truth teller. It means so much to us as a family this incredible outpouring of love and support that the world, literally the world, is giving to us."

The family did not disclose the date or cause of death.
