LOS ANGELES, Calif. --

Often-troubled country singer Mindy McCready is undergoing treatment at an unnamed rehab facility after suffering a miscarriage on July 16, a source close to the singer has confirmed to Access Hollywood.

The source told Access Hollywood the pregnancy was unplanned with an unidentified man that McCready had been involved with for “three months.”

McCready’s emotional reaction to the miscarriage set in motion the chain of events that resulted in her being admitted for care, the source added.

Access has also learned that McCready, 32, is being treated for “alcohol, substance abuse and emotional issues with the emotional issues being at the top of the list.”

The source said the singer is expected to undergo treatment for “probably a month.”

McCready flew to the facility, which is identified only as a rehab clinic often frequented by celebrities, yesterday on a commercial flight. Doctors at Vanderbilt University Medical Center, where McCready was treated after the miscarriage, recommended the facility for her.

This is the latest in a long string of troubles for McCready, who shot to stardom while barely out of her teens, but who, in recent years, has become better known for run-ins with the law, suicide attempts, problems with her mother and for an abusive relationship with a former boyfriend.

This latest incident comes at a time when McCready is trying to re-launch her career with new music, some of it composed during a months-long stay in a Nashville area jail in 2006 – 2007.

A reality show revolving around McCready also is reportedly in the planning stages.
