Grammy winner Mandisa Hundley, at 47

Mandisa Hundley, a gospel singer whose strong vocals were applauded on “American Idol” and who later won a Grammy Award for best contemporary Christian music album, was found dead at her home in Nashville on April 18. She was 47.

The Media Collective, which represented Ms. Hundley, confirmed her death and said in a statement that the cause was not known.

Ms. Hundley performed and produced music with Christian themes. She was a fan favorite on “American Idol” in 2006, but became the fourth of the 12 finalists to be eliminated.

As a soul singer, she spoke openly about her love of God, and her music resonated with fans.

Ms. Hundley famously stood up to “American Idol” judge Simon Cowell, who has a reputation for being intimidating. In her video interview for the show, she referred to her audition in Chicago, when Cowell, in an apparent joke about her weight, said after she left the room, “Do we have a bigger stage this year?”

Ms. Hundley said in the video that, despite the remark, she would still travel to Hollywood and face Cowell in the final judging.

“When I got to Hollywood, I knew I had to put my game face on,” she said. “I knew that I would finally get to speak my piece.”

“You hurt me, and I cried,” she later told Cowell. “But I want you to know that I have forgiven you.” Cowell replied that he was “humbled,” and the two hugged.

Ms. Hundley told The Oklahoman in 2006 that her faith helped her overcome Cowell’s hurtful remark.

“Food has always been a problem for me,” she said. “When Simon first made the comments, it was a nightmare. But God turned it around. Those words became the impetus I needed to kick-start my plan to live a more healthful lifestyle and get my eating under control.”

She went on to record several albums. Her first was “True Beauty,” in 2007. Her 2013 Grammy winning album, “Overcomer,” debuted at No. 1 on the Billboard Christian Albums Chart. It was her first Grammy Award after three nominations.
