Serena from A loser like me recreates the make-up of Katy Perry in her This Is How We Do music video and gives her a grunge makeover.

Katy Perry is probably my favourite Hollywood Star right now, she's funny and sexy at the same time, she's edgy and cute.. I love her style cause it just reflects these characteristics at the same time! I'd love to give her a makeover cause she's such a chameleonic woman, she's rocked every single look you could possibly imagine: she's a california girl, she can roar like a lion and cast a perfect storm and her love is extraterrestrial. So the real challenge was to find something not too sophisticated that everyone could recreate and wear but that I hope she would still appreciate and like.

Khami recreates the makeup of Demi Lovato and gives her a blues-y babe makeover.

What I like about Demi’s style is her fluidity with looks. She can go from flirty and feminine to totally glam rock and she pulls it all off. She is unapologetically herself, both in style and the way she carries herself, and I think that’s what I love the most.

KatieAlves recreates the colourful makeup of Katy Perry and gives her a makeover inspired by her Roar music video.

I love how fun and colourful Katy Perry's style can be. Seeing some of her outfits from her tours is jaw dropping sometimes. The creativity is amazing! It's interesting to see how many different styles she can pull off. She's got her crazy, colourful side with cupcakes and candies. Then she can have a super glamorous look then switch it up and go dark, punky and gothic. It's always a surprise with her! Katy Perry's style is quite similar to mine. So doing a makeup for her would be amazing. I feel like she would be up for just about anything. She wouldn't be too shy to wear something absolutely out of this world, which is something a makeup artist always dreams of!
