Katy Perry has dismissed suggestion that her new album will be shrouded in darkness.

The singer's recent promotional campaign saw the US star shed her fluffy 'Teenage Dream' era in favour of a more mature look and personality.

However, she told MTV that her upcoming record 'Prism' - which will see the light of day on October 22 - isn't overly dark. Perry said:

"There's not really any darkness on the record. There's definitely some textures and colours but I think I was saying that when I was going through a different phase, but I really let that light in."

She added: "The reason why I called this record 'Prism' is because I actually finally let the light in and then I was able to create all these songs that were inspired by letting the light in and doing some self-reflection and just kind of working on myself. I felt very prismatic because of that; I feel like now I get to show these songs off and share these songs with the listeners and it's almost like I get to beam the colours that I've experienced out from me."
