Corinne Olympios was drinking and taking prescription drugs at one point during her short-lived time on Bachelor in Paradise, a source claims to ET.
Bachelor in Paradise resumed production on season four last month after concluding that no misconduct occurred between Olympios and another contestant, DeMario Jackson. According to our source, Olympios was never unconscious during filming of the reality show, however, she was allegedly blacked out from drinking alcohol and taking prescription drugs.
"Corinne's condition was exacerbated by the drinking and taking the prescribed medication," the source claims.

Olympios' rep had no comment on the allegations. ET has also reached out to Olympios' lawyer.
ET's Lauren Zima spoke with current Bachelorette Rachel Lindsay -- who appeared with Olympios on the last season of The Bachelor -- on Monday, who said she had "definitely reached out" to her friend and former cast mate.
"She's OK," Lindsay shared. "She's surrounding herself with her loved ones, that's great. She's picking up the pieces and she's moving on."
Last week, Olympios announced in a statement via her rep, Stan Rosenfield, that she will be appearing on Bachelor in Paradise's upcoming season four reunion show. Jackson also previously confirmed he would be appearing on the reunion show as well.
The news comes after Olympios stated late last month that her own team's investigation into what happened on the Bachelor in Paradise set had been completed to her satisfaction.

"While I never filed complaints or accusations against anyone associated with Bachelor in Paradise, my team and I felt it was very important to be thorough in getting to the bottom of what had occurred," she said in a statement to ET. "I felt victimized by the fact that others were judging me through conflicting and unsubstantiated reports, while I myself had no recollection of the events that transpired."
