Miley goes all grown up and serious with her new single, but are her Hoe Down Throw Down days over?

Miley Cyrus has had quite a year romantically, breaking up with boyfriend Justin Gaston and being linked to ex Nick Jonas, but her new song has nothing to do with any of her past crushes...phew!

When I Look at You is from the soundtrack to her new movie The Last Song and is all about the relationship between her character Veronica and co-star Liam Hemsworth.

It's one of Miley's slow, power ballads, but is it as good as The Climb?  You decide...

Miley will be off on her first world tour on 14 September, with Metro Station as support. Will you be going to see her when she hits the UK in December? Are you loving her new tune?
