Little Girl's Epic Reaction to Katy Perry's Song Goes Viral

For all parents who've been through long drives with bawling babies, here's a trick that just might work for you. All you have to do is play a Katy Perry song - it seemed to have brought smiles for this family in the adorable video below.

Strapped in her car seat, this cute little golden-haired baby shows her discomfort by howling on top of her voice. However, only seconds later the scene completely changes when she hears Dark Horse playing on the car's sound system. You can see the switch in her reaction as her frown just completely vanishes away.

It's easy to tell that she must really be enjoying the song; she dances, bobs her head and even shares an appreciative toothy smile with the camera.

Just watch this video. We're sure it'll amaze you.
