The popular country singer led an often troubled life.
Mindy McCready's boyfriend David Wilson committed suicide, the singer's rep confirms to FOX411.
The Cleburne County Arkansas Sheriff’s Office told the Daily News that authorities responded to his home on Sunday after a receiving a report of a self-inflicted gunshot wound.
Wilson, 34, is the father of a 9-month old son with McCready.
"Today, we mourn the loss of my life partner and my children's father, David Wilson," McCready said in a statement to FOX411. "David was my soulmate; he was a caregiver and guiding hand to our sons, Zander and Zayne. He was a precious gift from God to all of us and, yesterday, he returned home and is now with his mother and father."
McCready, 37, found fame in the mid-1990s when she moved to Nashville at the age of 18, armed with only her karaoke tapes. Her first album, "Ten Thousand Angels," sold two million copies.
Her next four albums weren't as successful. Her personal troubles began encroaching on her professional success. According to her website, she suffers from severe depression.
McCready fought the release of a tape in which she reportedly talked about former Boston Red Sox and New York Yankees pitcher Roger Clemens, with whom she had an affair as a teenager.
In August 2011, she filed a libel suit against her mother and the National Enquirer's parent company, American Media Inc., over a story published in the tabloid newspaper that quoted Inge.
And in 2008, McCready was admitted to a hospital after police said she cut her wrists and took several pills in a suicide attempt.
During the TV show "Celebrity Rehab 3" in 2010, McCready came off as a sympathetic figure, and host Dr. Drew Pinsky called her an angel in the season finale.
