Eva Evans, a popular TikTok star and creator of the web comedy series "Club Rat," has passed away at the age of 29. Her sister Lila announced the news on Instagram on April 21, but the cause of death hasn't been disclosed.

My family got the heartbreaking news yesterday that my amazing, talented, compassionate, and funny sister Eva has passed away, her sister wrote. "Even after a full day, I'm caught in a loop of disbelief and acceptance, so I can only imagine how hard this is for everyone to comprehend.

She mentioned that a celebration of Evans' life would take place on April 23.

"I wish Eva were here now because she'd find better words and know how to express what I can't," she added.

A few hours later, her sister shared an emotional video where she read aloud a birthday card that Evans had written for her. Addressing her audience, she said, "Thank you for reaching out and for the tremendous support to my family, it means so much."

In a follow-up Instagram post, Evans' sister announced that "due to the overwhelming response to Eva's celebration of life," a church service in downtown Manhattan had been organized to "include anyone who loved Eva," along with a smaller gathering for close family and friends.

Evans, a popular TikTok star with over 300,000 followers, was known for her witty and darkly humorous videos about navigating life and relationships in New York City.

She also created and starred in the Amazon Prime series "Club Rat," a comedy about an influencer who tries to start dating again in New York City after her breakup video goes viral.

Tributes have been flooding in for Evans on social media.

Julia Fox posted a tearful TikTok video about Evans' death, saying, "I always saw her as a little sister, and I know she looked up to me. She passed away so young. She still had so much to accomplish."

Photographer Ashley Armitage also shared a heartfelt tribute to Evans on Instagram.

"I loved Eva from the moment I met her. The world is less bright and far less funny without her, and I don't think I've laughed harder with anyone else. Eva was smart, hilarious, creative, caring, magnetic, confident," she wrote.

"She moved through life with love and laughter," she continued. "She had such a magnetic personality; people were drawn to her and wanted to be part of her world. Eva was open and vulnerable, and she made people feel like they'd known her for years, even if they had just met."
