Rosie O’Donnell’s long-troubled daughter was reportedly checked into a Long Island hospital after overdosing on drugs.

Chelsea O’Donnell, who has struggled with mental illness and drug abuse, was rushed to the emergency room late Monday night, according to Radar Online.

The 19-year-old’s TV star mom was not yet at her bedside and a rep for the host told Radar that she is “not commenting” on the incident.

According to E! News, Chelsea was “alert and awake” and undergoing a psychiatric evaluation.

Chelsea will be evaluated by social workers, psychiatrists and other mental-health professionals, the E! report said.

Rosie and Chelsea were temporarily estranged last summer after Chelsea, who had not been taking her medication, was reported missing. She was eventually found unharmed at the home of an older alleged heroin dealer.
