Emily Willis — a famous porn star — was hospitalized after an apparent overdose, and she’s in bad shape as doctors work on nursing her back to health … 360aproko has learned.

Law enforcement sources tell us the adult film actress was transported to a medical facility in Thousand Oaks, CA Sunday — this after a call for service reporting a possible OD. We’re told the report came in for an unresponsive 25-year-old … whom we’ve confirmed is Emily.

Our sources tell us she’s currently in the critical care unit at the hospital — although her exact condition is unknown.

One other notable tidbit — Emily was actually transported from a well-known celeb rehab location in Malibu … where she appears to have been receiving treatment for addiction.

Emily has been working in the porn biz since at least 2017 — and she’s been a rising star since then … having appeared in countless videos and productions since then, and collaborating with a ton of recognizable brands like Reality Kings, Evil Angel and more.

She’s also done work for Penthouse Magazine — and actually won Pet of the Month in 2019. Emily has also made waves at AVN Awards in recent years … so she’s a known name.

Emily has even rubbed shoulders with big-time social media stars — including David Dobrik. She was embroiled in a bit of controversy in 2021, when she filed a defamation suit against a bunch of other porn stars … alleging they were trashing her on social media apps.

Since then, Emily has kept busy with a lot of different kinds of projects, including a handful outside of porn — she’s appeared in music videos and other promotional modeling campaigns.

Like we said … she’s incredibly popular — with over 2 million followers on Instagram alone.

We’ve reached out to her camp for comment … so far, no word back.
