Katy Perry throws possibly the best throwback Thursday snap ever, predicts fame ten years early #TheElitePartyInJuly #IRepEntertain9jarBlog #FreeTwitterTrendMachine via @myentertain9jar

Singer looks like she was destined to be a star judging by her T-shirt, is being sued by religious rappers

KATY Perry likes to change her look more than most. She's had every hair colour going and loves nothing more than a costume change.

But we've never seen the Firework hitmaker look like this before.

The 29-year-old singer posted a Throwback Thursday snap onto her Instagram account yesterday, and we have to say, it's a cracker.

It looks like Katy had something of a premonition in her youth about her forthcoming fame: she's wearing a T-shirt emblazoned with the words, POP STAR, many years before she recorded I Kissed A Girl.

Katy captioned the snap: "#TBT me at 14 or 15 wearing a bedazzled shirt that said POP STAR. (with chocolate in my teeth yerp)".

Katy is currently on the US leg of her Prismatic world tour, where she is wowing fans with hits including Roar and Dark Horse.

But not everybody's happy – she's being sued by a collection of Christian hip-hop stars who claim that Dark Horse rips off their song Joyful Noise.

She certainly didn't see that coming.
