30 HOLLYWOOD CELEBS WHOSE REAL NAMES YOU WILL NEVER GUESS

It's common practice in Hollywood for stars to ditch the names on their birth certificates for a fresh new moniker. Read on to learn what Miley Cyrus, Frank Ocean and more were originally called.

Believe it or not, a lot of celebs change their names when they enter the entertainment industry. Whether it's because fans have a crazy hard time pronouncing them, or there's a childhood nickname that just stuck over the years, plenty of famous faces switch up their monikers.

Some stars, like Miley Cyrus and Frank

Ocean, have even made their name change legal. The way Frank Ocean sees it, "None of us are our names. If you don't like your name then change your name."

And it seems like a lot of other singers and actors agree with him.

Jennifer Aniston, Lady Gaga and even Jamie Foxx reinvented themselves by making the switch years ago, and now it's weird to even think that they could go by anything other than their stage names.

Keep scrolling to see the 30 stars who have made a living under a new moniker!

Eilleen Regina Edwards

Shania Twain shared the origin story of her stage name during an appearance on Apple Music's Home Now Radio: "In short, I was born, Eilleen Regina Edwards, and then I was adopted and I became Eilleen Regina Twain. Then I became a professional singer and I needed a stage name that sounded a little less like my grandmother's name, because I'm named after my grandmother, both my grandmothers, Eilleen and Regina. I think, in my mind, I was just not really wanting to be called my grandmother's name onstage, so I decided to change it to Shania Twain. I met somebody with the name Shania, thought it was beautiful, and Shania Twain was born."

Belcalis Almanzar

Cardi B took on the name Bacardi after

family and friends started calling her sister Hennessy. Later on she shortened the name to something that suited her quite a bit more.

Jelena Noura Hadid

Oddly enough, Gigi Hadid got her stage name in school when the teacher would confuse her and a girl named Helena. Since her mom called her "gigi" as a term of endearment at home, she told the teacher to just call her Gigi and it simply stuck.

Mark Vincent

If you're looking for an explosive action star name, how about Vin Diesel instead?

Rachel Meghan Markle

Before she became the Duchess of

Sussex, Meghan Markle was briefly of known as Rachel.

Destiny Hope Cyrus

Miley Cyrus' bright smile is what inspired her childhood nickname, Smiley. Eventually the name was shortened to Miley and it stuck.

Peter Gene Hernandez

Apparently the singer looked more like a Bruno than a Peter, so one day his dad started calling him Bruno. Ever since, he has been known as Bruno Mars.

Stefani Germanotta

Before the meat dresses and chart topping music, Lady Gaga was just an everyday girl from New York.

Laura Jeanne Reese Witherspoon

Turns out Reese isn't even Reese

Witherspoon's middle name. The actress chose the moniker in honor of her mother, whose maiden name is Reese.

Elizabeth Woolridge Grant

Every artist has an alter ego, and Lana Del Rey just happens to be the persona of choice for the singer.

Christopher Edwin Breaux 

In 2014, Frank Ocean legally changed his name because, why not?

Elizabeth Stamatina 

Fey A little known fact about 30 Rock's Tina Fey is that she is actually named Elizabeth. The comedian made a not so subtle tribute to her birth name by naming her character Liz Lemon.

Calvin Broadus

This pioneer of West Coast rap would later go on to be known as Snoop Dogg.

Ella Marija Lani Yelich-O'Connor

Turns out the "Royals" singer is really into learning about the aristocracy, hence the reason why she chose the name Lorde, but with a feminine 'e.'

Enrique Morales

Before he started shaking his bonbon for the masses, music superstar Ricky Martin went by this everyday name.

Amethyst Kelly

It's hard to believe that Iggy Azalea was born Amethyst Kelly!

Adam Richard Wiles

Fans were confused when Taylor Swift thanked then-boyfriend Adam in an acceptance speech, which lead people to

the discovery that Calvin Harris is simply a stage name. The DJ told Shortlist magazine he chose the name because his first single was more soulful and wanted something a bit more "racially ambiguous."

Jennifer Anastassakis

Before she became a household name,

this was what erstwhile Friend Jennifer

Aniston answered to.

Alicia Augello Cook

Alicia Keys didn't always have such a musical name.

Thomas Mapother IV

Before he became arguably the biggest movie star in the world, Tom Cruise went by this name.

Natalie Hershlag

Back when she was born in 1980, this was how the future bigtime actress Natalie Portman greeted the world.

Amanda Lee Rogers

Before she became a big-time TV star and married Ellen DeGeneres, this was the name Portia de Rossi answered to.

Reginald Dwight

Guess music superstar Elton John didn't think his original name would be a hit with audiences.

Nicole Camilla Escovedo

Check former Paris Hilton BFF Nicole

Richie's birth certificate and this is the

name you'll see.

Paul Hewson

All it took was a nickname from some high school friends, and U2 frontman Bono's famous moniker was born.

Tara Patrick

We agree Carmen Electra is much more effective when it comes to selling a sexy Baywatch persona.

Eric Bishop

True, Jamie Foxx just seems more fitting for an Oscar-winning Hollywood party guy.

Demetria Gene Guynes

Before she'd starred in dozens of huge

Hollywood movies and married two Tinseltown A-listers, this was the name

Demi Moore went by.

Shawn Carter

Jay-Z is definitely a more fitting name for a hip-hop impressario.

Brian Warner

If you want to work a ghoulish persona, we agree, a name like Marilyn Manson will work much better.
