(Relaxnews) – American pop star Katy Perry has shared 90-second snippets of each song from her upcoming album “Prism” via iTunes, a few days before its worldwide release.

Perry announced the news via Twitter on October 17, followed by the tweet: “I’m really excited to share these songs with you all…I’m so proud of them. Will u let me know what u think & how they make u feel please?”

While “Prism” is out Friday in a handful of countries, it hits the UK and France October 21, followed by a worldwide release a day later.

The album contains the singles “Roar,” which topped charts this summer, and “Unconditionally,” released in the US on October 16.

Announced earlier this week, the 28-year-old singer has just become the latest face for CoverGirl cosmetics.
