Scary news for Brett Rossi!

The former adult film star and ex-fiancée of Charlie Sheen was reportedly rushed to the hospital over the weekend after overdosing on an unknown substance.

According to Radar Online, the 25-year-old was found unresponsive in her California home by a close friend.  

"It was an overdose," an insider told the publication. "It is not known what she overdosed on."

Rossi was taken to Cedars-Sinai Medical Center in Los Angeles where her stomach was allegedly pumped. She reportedly spent one night in the intensive care unit before being transferred to a regular care unit.

Sheen's rep told E! News that the "Anger Management" star is aware of Rossi's overdose.

"Charlie and Scotty have been in communication and Charlie still has a tremendous fondness for Scotty and continues to wish her all the best," said the rep.

Rossi was formerly scheduled to marry Sheen later this month and was rumored to be changing her name to Scottine Sheen. The "Two and a Half Men" star broke off the engagement to Rossi in October, citing his commitment to his children as the reason for the split.

"Scotty and I had a great year together as we traveled the world and crossed a lot of things off our bucket list," Sheen said in a statement to E! News. "She's a terrific gal-but we've mutually decided to go our separate ways and not spend the rest of our lives together."

"I've decided that my children deserve my focus more than a relationship does right now," he added. "I still have a tremendous fondness for Scotty and I wish her all the best."
