Grace VanderWaal’s latest look is worthy of a golden buzzer.

The America’s Got Talent alum was shining bright as she celebrated her 21st birthday Jan. 15 in a glittery gown fit for the festive occasion.

In an Instagram carousel posted on her big day, the singer—who won the talent competition series in 2016 at just 12 years old—modeled a sheer beige minidress covered in sparkly sequins. Across several photos and videos, she struck several playful poses for the camera, alternately winking and blowing kisses.
