Walker joined the Good Morning America family for their ‘Frozen’ sing along.
She became Elsa for Alex Boye's recent YouTube video covering "Let It Go." Over 18 million people have watched this video online. That attention got her Wednesday’s invite.
Lexi isn't new to impressing with her unreal talent. We first heard about Lexi last year.
She won the Canyon School District's “Canyon Idol" competition. Winning that gave her the chance to sing the national anthem at a real game.
A video of that performance went viral online marking the beginning of her discovery. Since then she has been sharing her talents with anyone and everyone who will listen.
ABC4 met up with Lexi a few months ago, she summed up pretty simply why she loves to sing.
We just love to listen to this little Utahn impressing the world.
Watch the sing-a-long below:
