Brett Rossi, Charlie Sheen’s ex fiancé, had to be hospitalized over the weekend.

According to Radar Online, Rossi, who also goes by the name of Scottine Sheen, was found unresponsive at her California home by a close friend.

“It was an overdose,” a source told the website. “It is not known what she overdosed on.”

According to the source, Rossi was rushed to Cedars-Sinai Medical where she had her stomach pumped and then spent the night in the intensive care unit.

While one source revealed that Rossi had overdosed, Us Weekly explained that she was hospitalized due to an adverse reaction to a newly prescribed medication.

“Her hospital stay was due to an adverse reaction to a newly prescribed medication,” another source told Us. “The rumors that she had her stomach pumped due to an overdose are completely false. Scottine has always been an advocate for living a healthy, sober lifestyle and has never had a history of substance abuse in her past.”

“Scottine has chosen not to comment on anything regarding her personal life and has only asked that the media please respect her privacy during this time,” the source added.

Sheen and Rossi called it quits in mid-October. “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 at the time of their break up. “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.”

While they are not together, Sheen did reach out to his ex after the incident. “Charlie and Scotty have been in communication and Charlie still has a tremendous fondness for Scotty and continues to wish her all the best,” Sheen’s rep told E! News.
