Pacifiers, naptime or cookies are usually good ways to cheer up a crying baby, but this baby prefers a more musical approach.
In a video posted Monday on YouTube, a tiny baby in a car-seat is filmed having a tantrum. Crying and shaking, she begs for attention until she gets what she really wants: Katy Perry.
The second Perry's new "Dark Horse" song comes on the radio she turns from glum to giddy and dances and sings along to the catchy song.
Forget a lullaby. Hopefully the next time the little girl gets upset, the pop-star is ready for action.
