Adele stunned by fan's singing, turns out to be Christian Grammy-nominated artist Jamie Grace

A random fan that renowned singer Adele pulled up onstage at her concert in California recently, left the British singer stunned with her exceptional singing voice, however, that person turned out to be Christian Grammy-nominated singer, Jamie Grace.

Jamie Grace posted videos on social media of her duet with the highly acclaimed British singer during Adele's concert at the Staples Centre in Los Angeles on Tuesday night.

"She was being super interactive with her fans," Grace told ABC News, "and then she looked at me and I said, 'Do you want to sing together?' And she said, 'Okay, come up here!' So I went up there."

Grace's video footage captured her impromptu performance of Adele's song "Remedy" and "I Can't Help Falling in Love With You" by Elvis Presley. The 28-year-old singer-songwriter, who keeps a staggering 98 awards and 198 nominations under her name, also appeared hands-over-chest astounded by her fan's singing ability. Adele embraced Grace at the end of the latter's performance.

Adele's concert fan turned out to be the 24-year-old Christian singer, rapper, and songwriter from Atlanta, who received a Grammy nomination four years ago for her 2011 song "Hold Me" and won the 2012 Dove Award for New Artist of the Year.

Grace shared Saturday on her Facebook page that she still had it tough despite her musical recognitions to the point that she already thought of retiring. She added that she's been seeking help from a Christian counselor since last year.

"I've been trying to process why I feel like God is calling me to this amazing purpose yet for some reason things just aren't working out," Grace wrote.

She said that being on stage with Adele "was a reminder and an assurance that I do have a voice and the voice does matter."

The Christian singer also shared her dream of writing songs with Adele or of how she, her sister, and Adele could do a "three-part harmony," where Adele could "take the lead," of course.

"I'm a dreamer so I have no shame," said Grace.
