Mara Justine sings 'Perfect' on America's Got Talent 2014 Top 12 (VIDEO)

Mara Justine sang 'Perfect' on the America's Got Talent 2014 Top 12.

I thought this started off pretty shaky and off-key (at least to my ears), but Mara recovers beautifully and delivers one of my favorite vocal performances of the entire competition.

SERIOUSLY, HOW IS THIS GIRL ONLY 12?!?! Just such a sensational performance. And Mara is crying to see the judges giving her a standing ovation right as the song ends. She's so frigging endearing.

Mel B calls the performance "perfect" and expresses how impressed she was by the vocal, the key change, and everything about the performance. Howard feels she's "graduated from America's Got Talent College," while Howie feels that although Mara is absolutely great, everyone tonight is great. If America wants to keep this greatness around, they'll have to vote her through. Howie does get a quip in, though, by noting that no little girl has ever "worn Pink" like Mara just did. Heidi, lastly, says that Mara should never doubt herself for one moment. And Heidi's right. Such a wonderful performance, from one of the most likable contestants in this entire competition. I really hope she goes through.

But what do you think of Mara Justine?
