Mindy McCready denies killing boyfriend David Wilson

Mindy McCready opens up about the death of her boyfriend, producer/musician David Wilson, in a new interview with NBC's Andrea Canning of "Dateline."

Authorities said Wilson was found dead of a gunshot wound on Jan. 14 on the porch of the couple's home in Heber Springs, Ark. At the time, police said they responded to Wilson's home after receiving a report of a self-inflicted gunshot. The investigation, though, remains open, and murder hasn't been ruled out.

When Canning sat down with the country singer, she asked, "For the record, did you kill David? Did you shoot David?"

"Oh my God, no. Oh my God, no. He was my life," McCready, said. "We were each other's life."

When Canning asked if McCready, 38, was "100 percent" certain that Wilson had committed suicide and had not been murdered, McCready said, "I don't know."

Calling Wilson her "soul mate," McCready also detailed the moment during which she said she first found Wilson's body.

"I just started screaming, calling 911," she said. "I lay down next to him and just just pleaded with him not to die."

She also blasted reports that Wilson had been cheating on her.

"David was not having an affair with another woman," she said. "That is absolutely totally untrue."

Police, meanwhile, haven't named McCready, or anyone else, as a suspect in Wilson's death. Authorities are awaiting lab results in order to determine if Wilson's death was caused by a self-inflicted gunshot wound or murder.

McCready made headlines in 2011 in the wake of controversy surrounding custody over her son, 7-year-old Zander, whose father is country artist Bill McKnight.

McCready's debut album came out in 1996. She released her most recent studio album, "I'm Still Here," in 2010.

The "Today" show aired a portion of the interview on Tuesday morning. Watch some of it below:
