The 28-year-old pop star had no idea she brought a GRAMMY-nominated artist up onstage!
Hello from the other side, indeed!
During one of Adele's sold-out shows at the Staples Center in Los Angeles on Tuesday, the 28-year-old pop star handed the microphone to a fan in the audience -- and was incredibly impressed by her pipes.

The "Hello" singer brought up Jamie Grace to the stage, but was not expecting to hear her belt out these flawless notes:
Turns out, the 24-year-old Georgia native is a GRAMMY-nominated Christian artist. Her debut song, "Hold Me," landed her a nomination for Best Contemporary Christian Song in 2012.
Back in March, a similar situation happened at Rihanna's show in Cincinnati, Ohio. RiRi was blown away when Terah Jay, who was sitting front row, took over the mic and sang his best rendition of "FourFiveSeconds."

Adele is no stranger to inviting concertgoers onstage -- she recently burped in a fan's face and hilariously blamed it on a burger, accidentally kissed one of them on the lips, helped a young girl propose to her boyfriend and told someone to "suck my d**k."
