America's Got Talent: Grace VanderWaal covers Meghan Trainor

Remember that young lady Simon Cowell compared to Taylor Swift a little while ago? Well, Grace VanderWaal won't be back on America's Got Talent for a few more weeks, but she's released a new video on YouTube that's no less impressive than her ukulele performance a few weeks ago.

Dressed casually in shorts and a unicorn headband, the wise 12-year-old is just chilling on her porch with her dog as she declares, "I'm having a pajamas and no-makeup day because this is just, like, a self-love day and everyone needs a day like that. And this song matches that theme."

That song, we soon learn, is a cover Meghan Trainor's "All About That Bass," but VanderWaal certainly makes it her own with her unique vocal stylings and ukulele strumming. The dog clearly digs it, and so do we.

Following her Golden Buzzer-earning audition on AGT — during which she sang an original tune and had Cowell saying, "I think you are the next Taylor Swift" — VanderWaal admitted to EW that she practices in front of the mirror before performances. But, when it comes to her return to the AGT stage, she's just "so excited."

Watch the new video above and relive VanderWaal's AGT audition below.

America's Got Talent airs Tuesdays and Wednesdays at 8 p.m. on NBC.
