NEW YORK, Jan. 29 (UPI) -- U.S. country singer Mindy McCready said on TV's "Dateline" she didn't kill David Wilson, but isn't convinced her boyfriend fatally shot himself either.
Wilson, 34, was a singer-songwriter and the father of McCready's infant son. He was found dead of an apparent self-inflicted gunshot wound Jan. 13 and his death remains under investigation.
Asked in a soon-to-air "Dateline" interview if she shot Wilson, McCready replied: "Oh, my God, no. Oh, my God, no. ... He was my life. We were each other's life."
Pressed to disclose whether she believed "100 percent" Wilson committed suicide or whether he might have been murdered, the singer grew quiet, then said, "I don't know."
McCready also denied rumors claiming Wilson had cheated on her shortly before he died.
"David was not having an affair with another woman. That is absolutely totally untrue," McCready said.
"I've never gone through anything this painful, nor will I ever again go through anything as painful," she added.
The "Dateline" interview was excerpted on Tuesday's edition of the "Today" show.
E! News said Wilson's friends are baffled by why the new father would want to kill himself. They also said McCready did not attend a Jan. 19 memorial they arranged for him.
McCready's once-bright career has been sidelined in recent years by her battles with substance abuse, suicide attempts and legal woes.

Dior: Lawrence did not have a wardrobe malfunction at the SAG Awards
LOS ANGELES, Jan. 29 (UPI) -- A representative for Dior says Jennifer Lawrence did not suffer a wardrobe malfunction at the Screen Actors Guild Awards ceremony in Los Angeles Sunday.
Lawrence, 22, looked stunning in the blue gown she wore to the event, but the frock appeared to come apart, leaving her upper thighs bare, when she stood to collect her Best Actress statuette for her work in the film "Silver Linings Playbook."
"The dress is made with different levels of tulle and satin and that is what the viewers saw when Jennifer lifted her dress slightly," a representative from the Dior fashion house told EW.com Monday. "It was not ripped and there was no malfunction ... it was the design of the gown."
