The 'Teenage Dream' star's co-writer says fans have no idea what to expect from her next record.

Katy Perry's new album won't all be similar to new song 'Roar' and will have each song being like "its own little movie", songwriter Bonnie McKee has revealed.

The 'American Girl' singer has worked regularly with Katy across her last album 'Teenage Dream' and upcoming record 'Prism', and says fans shouldn't be so sure about what to expect from the US star's next release.

"It's kind of like every song is its own little movie," Bonnie McKee teased to MTV News this week. "So [Roar] is 'Rocky' and also kind of jungle-y and cat-themed.

"And then each song has its own little movie and its own visual to go along with it," she explained. "So I wouldn't say it's all going to be like this.

"Like the next one, as far as I know, is going to be a big one too, I'm really excited for the next one," Bonnie teased. "[The song is] really colourful and really bright.

Katy Perry returned with new single 'Roar' last weekend going on to top charts around the world, while stars including will.i.am have praised the track as "freaking awesome".
