Mindy McCready, the mother of two young sons, has died of an apparent suicide, People.com said Sunday. The troubled U.S. country singer was 37.
The recording artist's once-bright career has been eclipsed in recent years by her battle with drug addiction, legal woes and erratic behavior.
Her boyfriend, singer-songwriter David Wilson, died of a gunshot wound last month. It is still unclear whether it was a suicide, homicide or accident.
McCready has denied any involvement in his death.
Her two sons -- ages 6 years and 10 months -- were placed in foster care after a judge ordered the singer to go into rehab three weeks after Wilson died.
Her family said she had begun using drugs again.
