Girl With Autism Brings The House Down In This Amazing Duet With Adele

"She has a different persona when she is on stage."

When 12-year-old Emily Tammam attended Adele's concert this week, she probably never thought she would wind up on stage with her.

While it may seem like fantasy, that's exactly what happened when Emily and her father from Whitefield in Greater Manchester, England attended Adele's show at Manchester Arena.

Emily, who suffers from attention deficit hyperactivity disorder (ADHD), autism, and a limb-weakening disease called Ehlers-Danlos syndrome, attended the show with a sign that simply said, "It is my dream to sing with Adele," and then magic happened.

Towards the end of the show, Adele had the lights turned up and was reading the signs in the crowd. That's when she saw Emily's sign and told her to come up on stage to sing "Someone Like You" with her.

Her father Ray told the Manchester Evening News, "Adele is her favorite singer and 'Someone Like You' is her favorite song." Although Emily has faced a litany of challenges, her dad added that, "She has a constant struggle with social situations, but amazingly she manages to sing in public."

You can watch Emily completely nail her performance note for note in the video below:
