I hope Kerli writes it for them cos Demi's only good song is written by her so it'd be nice if the collab was good

You mean her most overrated song

Are you for real? You obviously haven't heard her albums and the song she has written, Skyscraper did well was because of Demi's Vocals and the emotion she put to the song not because of the lyrics

So if she sang 'Suzanne' by Plan B with the same emotion it would have been just as beautiful?

Have you heard 'For The Love Of A Daighter'?
... That's what I thought
