So, Ashlee Simpson is back: new nose, new rock on her finger and, most excitingly of all, new sound. In fact, Sister of Jessica has ditched the slightly dour radio rawk of yore - remember 'Pieces of Me'? - in favour of a somewhat unlikely Timbaland hook-up. Yup, him again.

The oddly-titled 'Outta My Head (Ay Ya Ya)' is not unlike Cyndi Lauper for the noughties: all chugging new wave guitar, kooky hooks and fresh-as-morning-dew production. The video, featuring Ashlee flying on a Rubik's Cube, Ashlee being set upon by The Borrowers and Ashlee being sectioned, is also bursting with ideas. Et voila!



'Outta My Head' didn't exactly set the US charts on fire, but can it do the business over here? Just hit the usual button to tell us what you think.
