History's seen a lot of big voices in little packages
, and it's about to see another one Sunday night on America's Got Talent
Mara Justine is 11 years old. She's from Galloway Township, outside of Atlantic City, New Jersey, and don't be fooled by the fact that she kind of looks like she's trying out for a reboot of Matilda
– wait until you hear her sing.
She's studied with Linwood, New Jersey, vocal coach Sal Dupree for three years; Dupree told The Press of Atlantic City
that Justine is "really something special."
Watch the clip and judge for yourself, but we're inclined to agree.
"Audition Night" on America's Got Talent
airs Sunday at 9 p.m. on NBC.
