Can you believe the I Kissed a Girl singer was once so fresh and beachy? We love how healthy and happy Perry looks in 2006

In 2009 the pretty raven-haired star shook off her beach babe vibe in favour of a moody look. With hair lopped into a short, fringed bob and make up left pale and sultry, KP couldn't have looked more different

It's pretty hard to believe Katy Perry is actually a natural blonde, isn't it? The singer began the tough process of lightening her locks post-black hair dye for the premiere of the Smurfs in New York

Oh wait, yes she could. A year later Perry injected some pop back into her life with multi-coloured hair streaks and pink lipstick

Now a married lady, Katy arrived at the 2011 Grammy Awards glowing with perfect make up and centre-parted loose curls

Once she had managed to bleach her hair super-blonde, there was nothing stopping Katy tipping brightly coloured dye all over it. Perry opted for hot pink and oriental crystals at the American Music Awards in 2011

Post-Rusty, Katy Perry was ready to get her colour-on again. For the launch of her new eyelash range Katy chose vibrant blue with a brave short fringe and heavy make up

A look that divided most but we couldn't help but love it. She's got hair like a blue waterslide! What's not to love? Katy attended a awrds ceremony in Berlin rocking a strong blue quiff, Pepto Bismal-pink lips, giant lashes and loads of punky earrings

Towards the end of her marriage to Russell Brand Katy chose to ditch the OTT hair and make up, dialling it back for an appearacne with her then-hubby at a Benefit Gala in LA. We like the faint-pink blonde bob and pretty make up

Fun Katy's back! At the Nickelodeon Kid's Choice Awards this year Katy blew everyone away with her uber-neon ensemble. It might not be pretty, but it's definitely fun. Bright make up and streaky extensions finished her look

Later this year Katy changed things up again, going for a hippy-dippy vibe. Plummy locks were centre-parted and accessorised with flowers and make up went a shade darker with rich wine-y lips

But the hippy look isn't right for red carpet Katy so when the time came for her to tread the plush carpet for the premiere of her documentary Part of Me, KP opted for old-Hollywood glam with a dash of Perry pizazz. Statement red lips and full lashes looked fab against her pale skin and purple coiffed hair

Another Part of Me premiere, this time in London. Katy pulled her dark locks up into a sleek and OTM 60s bun ponytail and chose a rich make up palette. Pretty darn gorge. See what you're missing out on, Rusty? Here's hoping John Mayer treats KP right...
