I still mourn the death of Gaga and Kanye\'s Fame Kills project before it even began, and only recently heard about Britney\'s non-starting Original Doll venture. So, I got thinking about what other artistic endeavours by your faves have been sadly shelved before they got the opportunity to set the charts alight, change your lives, kill their career etc. A Girls Aloud in Bollywood album? Enya on the dancefloor? A follow up to Katy Perry\'s Christian album? A Britney/Yoko Ono collaboration? Discuss them here!
