Katy Perry is celebrating her 29th birthday today but yesterday she was busy posting a picture from her childhood.
But it wasn’t just any picture. It showed her in a sailor dress and with a haircut that we reckon everyone had at some point in their life.

The Roar singer captioned the adorable photograph: “#Throwbackthursday in my sailor moon dress!”
Katy wasn’t the only pop star to turn back the clock with an old snap this week. Beyoncé posted one of her younger self as well.
