No. 10: Sacha Baron Cohen / Ali G 2f3p6j

Comedian and actor Sacha Baron Cohen has a few alter egos: Borat and Bruno. But it was Ali G that launched him into stardom. Ali is a young man from the inner city, immersed in Jamaican culture and way of speaking. He is a ridiculous figure of fun but Sacha uses him to ask provoking questions in interviews with important people, like Donald Trump, Buzz Aldrin and John McCain.
No. 9: Eminem / Slim Shady 144s4m

Eminem and his alter ego would retire after 2005's Encore album, but both were back in this year's Relapse.
No. 8: Miley Cyrus / Hannah Montana 5331m

Hannah Montana is the rock-star alter ego that originated on Miley that contrasts with her down-to-earth "normal" self.
No. 7: Nick Twisp / Francoise 37372g

In the new movie Youth In Revolt, Michael technically also plays Carlotta, a third character in drag).
No. 6: Clark Kent/ Superman 6n2t50

There could be an entire list of superheroes with alter egos but Superman is one of the most iconic. As Clark Kent, Superman is the spectacle-wearing mild-mannered reporter for the Daily Planet. But quick as a flash he can change into his costume in a phone booth and fly to the rescue as Superman.
No. 5: Beyonce / Sasha Fierce 46j68

No. 4: Dr. Jekyll / Mr. Hyde 2i3j72

When Jekyll drinks the potion he becomes Mr. Edward Hyde, a cruel and violent man who stalks the streets of London at night.
No. 3: Mariah Carey / Mimi 4m614t

Mimi is Mariah Carey’s DIVA – but hasn’t Mariah been acting like a major diva (someone who needs someone else to wrap a towel around her when she gets out of the pool and hold an umberella over her head when it’s raining) ever since she lost her curly hair?
No. 2: Christina Aguilera / Xtina 624t18

Christina Aguilera decided to shed her wholesome image in 2002 with the release of her album Stripped. During this time, she referred to herself as Xtina, even getting a tattoo of her nickname on the back of her neck.
No. 1: Sabrina / The Teenage Witch 6s5n33

Ever since she started appearing in Archie Comics, sweet, blonde Sabrina has been hiding her alter ego – a teenage witch with magical powers – from her friends. Eventually, the character went on to have her own TV show, starring Melissa Joan Hart.
