Just two days after Katy Perry and Russell Brand celebrated their first wedding anniversary, the pinked haired one has another reason to celebrate - it's her birthday! And while The One That Got Away singer has a penchant for wearing sparkly, spangly ensembles that could only have been conjured in the imagination of a small child, she's actually turning 27 years of age.
We just hope that she has matured to a point where she does not fell compelled to dive into her birthday cake, as she did back in 2008 (see proof below).
And to celebrate Katy's big day, we compiled a gallery of her most memorable style looks - scroll down to see some of our favourites.
Why not pay homage to Katy's birthday by channelling a bit of her eccentric style (as a cheaper alternative you could always attach two bakewell tarts to your bra).
