katy perry still 13

Katy Perry loves to wear girlish costumes on stage.

She says many of her stage costumes reflect her taste from when she was a teenager.

The singer favours bright colours and playful stage costumes by brands like Moschino and Cavalli during her Prismatic World Tour.

'There's a lot of colour in my shows. I have so much fun with it.' She says

I'm going to be 30 at the end of this year, but I still feel like a 13-year-old.

Katy has recently released her music video- Roar!
