Entertainment Weekly can exclusively reveal details about Katy Perry’s upcoming EP “California Dreams” which is set to drop later this fall. Perry has been back in the studio with regular collaborator Dr. Luke and has also has been laying down some tracks with Max Martin, Timbaland, Pharrell and Bangladesh. The music is in the same vain as the Teenage Dream album however has a more “future-esque electro bubble rock” sound to it as Katy describes it. Trust Perry to invent her own genre of music!

Zimbio.com also have exclusive details on the collaboration that there has been whispers about for months. She is set to collaborate with Rihanna on the club banger “Let Loose“. The verses of the track give way to a thumping chorus that can only remind us of a 2011 version of Hollaback Girl. Its definitely worth the wait for fans of both parties and is a sure fire number 1. The EP will be released individually or as part of a repackaged Teenage Dream which will include the E.P. plus the original album with remixes of E.T. with Kanye West and a forthcoming remix of Last Friday Night (T.G.I.F) with youtube sensation Rebecca Black who features in the new video for Last Friday Night, thanks to matty.
