Katy Perry’s new album, Prism, is officially on its way.

ELLE’s cover star went offline – and on-road – to make the long-awaited announcement, splashing ‘Katy Perry - Prism - 10-22-13’ across a giant gold truck (what else?) driven around the streets of Los Angeles.

Translated to British English, that’s an official release date of 22 October for Katy’s third solo album – the follow-up to 2010’s Teenage Dream.

‘Find the #PRISM semi, take a picture and I'll RT you,’ KP promises her fans via Twitter. ‘Don't worry, Los Angeles is just the first stop on the map.’

No word yet as to whether it’ll find its way to London – but spot it here, and @ELLEUK will give you an RT, too.
