Katy Perry's Biggest Fan! Crying Tot Dances To 'Dark Horse'

No matter what the time, Katy Perry's youngest fan can never resist a good boogie!

We know, we hate long car rides too! But when your favourite song comes on you just can't resist doing a little jig.

This little girl's music taste is marvellous and she isn't even old enough to sing along to the tune yet!

Maybe a career in DJing is in order?

Watch as Katy Perry's 'Dark Horse' plays on the radio, turning this baby girl's frown upside down!
