Mindy McCready  passed away on Sunday at her home in Herber Springs, Ark. The country crooner apparently took her own life and died of a suspected self-inflicted gunshot to her head.

Mindy had tried to take her own life three times before, between 2005 and 2008.

Her death comes just a month after longtime boyfriend and father of her youngest son David Wilson also passed away. Wilson is believed to have shot himself on the same porch as McCready in the home they shared in Herber Springs. 

Mindy is the fifth celebrity to pass away after appearing on the MTV reality show, "Celebrity Rehab" with Dr. Drew Pinsky, the third from her season.

The 37-year-old leaves behind two young sons, Zander, 6, and infant Zane. It is still unclear where her boys were at the time of her death.

Remembering the singer, celebrities took to Twitter to share their condolences:
