TikTok Star Leah Smith Dead at 22 After Bone Cancer Battle

TikTok star Leah Smith has died after battling stage 4 bone cancer ... and her fans who've followed her journey on the app are devastated.

The content creator's boyfriend, Andrew, announced the sad news Monday -- posting an update to Leah's 500,000-plus followers ... revealing she passed away earlier that morning.

In his video -- which has already amassed millions of views -- Andrew thanked her fans for all their love and support throughout Leah's tough fight with cancer ... which she documented extensively. Fellow TikTokers Katylee Bailey, Issey Moloney, Miah Carter and Ami Charlize have all expressed their condolences to Leah's loved ones.

At the start of 2024, Leah, who often documented her cancer journey, shared that she was struggling amid her health battle ... as her sickness had left her bedridden. By February, the social media star had reentered the hospital due to extreme pain.

She shared at the time ... "I can’t even move to go to the toilet."

Shortly after this update, Leah confirmed that her cancer had spread and that new tumors had grown.

As her health continued to worsen, Leah hinted that she was reaching the end of her journey ... detailing the crushing pain she was experiencing since her meds had stopped working.

Leah's brother Liam and friend Vikki took over posting for the star in recent weeks. In fact, just 3 days ago, the latest update read that Leah was "still here and fighting."

Vikki has since confirmed that Leah's page will not be deactivated ... but will remain on TikTok to preserve the star's legacy. She was only 22.

RIP
