What do Miley, Beyonce, Eminem and David Bowie have in common?

I read an article today from cbc.ca that compared two of pop music's celebrity alter egos - the legendary rock star alien Ziggy Stardust (by quirky David Bowie) and the wholesome Hannah Montanna (played by real-life "singer", Miley Cyrus).

Plenty of stars have tried Bowie's 37 year old strategy, and most have failed miserably. May I remind you of Mariah Carey's empancipation of Mimi, or when Christina Aguilera went dirrty as Xtina, and the Shady side of Eminem. I really like the whole alter ego thing to tell you the truth. It gives an artist dimension - and in pop music you need something eccentric to make good entertainment. Stage performance is everything.. and what better than an alter ego to bring that out in a star? LOVE IT.

Thank you CBC for the picture!
