Do your thang, Mila Kunis!
This little girl is so insanely cute we can barely handle it.
The video starts out with just a standard whiney baby, cute little bow in her hair, strapped into her car seat, moments away from an epic crying fit.
Katy Perry's Dark Horse came on!!
This baby's face is incredible, the change is immediate. As soon as KP comes on, this baby's day instantly turns around.
That look of surprise and pure excitement comes over her face and we can't even stand it!
Also, listen for when the song goes "uh huh," this little girly totally nods her head "uh huh" at the perfect moment.
Check out the video (below) to see this amazingly young Katy Perry fan!
