From Sasha Fierce to Roman Zolanksi: 5 Bizarre Pop Star Alter Egos

If you're still having nightmares over Nicki Minaj's exorcism of her alter ego Roman Zolanksi, take note: Her alter egos are here to stay. The rapper channeled a demonized Roman Z. at the Grammys (to our terror!), but on better days she becomes Onika, Harajuku Barbie, Martha or Rosa. Talk about a split personality!

But Minaj isn't alone - literally - in her alter ego channeling. Here's a look at some of the strangest pop star alter egos of all time.

Lady Gaga- Jo Calderone

Lady Gaga decided to treat us to her greasy alter ego at the 2011 MTV Video Music Awards. The show's bizarre opener featured Gaga dressed as her alter ego, a Fonzie-wannabe named Jo Calderone. Gaga kept up the charade all night long with no costume changes, practically scaring the pants off of Video Vanguard Award winner Britney Spears and elderly actress Cloris Leachman.

Beyonce- Sasha Fierce

Who is Sasha Fierce? I am, says Beyonce. Long before she was Blue Ivy's mama, the pop diva created alter ego Sasha Fierce. In 2008 she told Marie Claire, "I've created an alter ego. Things I do when performing I would never do normally. I reveal things about myself that I wouldn't do in an interview. I have out-of-body experiences [on stage]. If I cut my leg, if I fall, I don't even feel it. I'm so fearless, I'm not aware of my face or my body." But in 2010, Beyonce told Allure Magazine she "killed" Sasha. "I don't need Sasha Fierce anymore, because I've grown and now I'm able to merge the two," she said.

Prince- Camille

Prince has always seemed to be in touch with his feminine side, but his alter ego Camille had a mind of her own. According to Stylus Magazine, Prince's high-voiced alter ego was created in the mid-1980s, with a solo album slated for a 1986 release. And while The Artist referred to Camille as a"he," many theorized that Camille was Prince's female personna. The album project was inevitably scrapped, but whenever you hear high-pitched sped up vocals on a Prince song, it could be Camille.

David Bowie - Ziggy Stardust

He introduced us to Major Tom, Aladdin Sane and the Thin White Duke, but David Bowie's most iconic alter ego is Ziggy Stardust. Bowie's androgynous Ziggy defined the early days of glam rock and the character's rise and fall was even documented in a concept album. In a 1990 interview with Q Magazine, Bowie said that British rocker Vince Taylor was the inspiration for the character of Ziggy Stardust.

Bono- MacPhisto

If you didn't think Bono could scare you, you must have missed U2's Zoo TV tour. Bono unleashed his devilish alter ego in the early 1990s and it manifested as a combination of a corrupted rock star and a satanic character. We're glad the U2 front man has since shelved the freaky white pancake makeup and red horns!
