Some of the most recognizable names in show business are not the celebrities’ birth names, and stories about how stars got their stage names are sometimes nearly as fascinating as their careers.
Lady Gaga

Real name: Stefani Joanne Angelina Germanotta
The pop singer was born with a fairly standard Italian-American name. She was inspired to use Lady Gaga from Queen’s song Radio Ga Ga when she started her music career. She has since become known for her outlandish outfits and theatrical performances, as well as chart-topping tracks like Poker Face and Bad Romance.
Bruno Mars

Real name: Peter Gene Hernandez
Musician Bruno Mars got his nickname from his father, who thought he looked like professional wrestler Bruno Sammartino as a child. He later added the name Mars to develop the stage name we know today. Born in Honolulu, Hawaii, Mars went on to perform hits including Just the Way You Are and Uptown Funk.
Marilyn Monroe

Birth name: Norma Jeane Mortenson
The platinum blonde bombshell wasn’t always known as Marilyn Monroe. When she first started acting, the Hollywood icon went by Norma Jeane Mortenson. Eventually, her mentor at the studio suggested Marilyn as a first name, and she combined it with her mother’s maiden name, Monroe. Monroe soon became world-famous for her glamorized and stylized look.
Elton John

Birth name: Reginald Kenneth Dwight
The legendary British singer Elton John was born Reginald Kenneth Dwight. He later decided to change his name to pay homage to musicians he worked with: Elton Dean and Long John Baldry. This was long before he became a worldwide sensation with songs like, such as Rocket Man and Your Song.
Whoopi Goldberg

Birth name: Caryn Elaine Johnson

Katy Perry

Birth name: Katheryn Elizabeth Hudson
Katy Perry used her birth name when she released a Christian music album (her first work) in 2001. She later changed her stage name to her mother’s maiden name to avoid confusion with actress Kate Hudson. This was before her biggest hits like I Kissed a Girl and Firework took the world by storm.
Jamie Foxx

Birth name: Eric Marlon Bishop
Jamie Foxx first changed his name when he was starting out doing stand-up comedy. He selected the unisex name Jamie because in those days female comedians often got the call to go on stage first. Foxx was chosen in homage to Redd Foxx. The name eventually took him from comedy clubs to an Academy Award-winning acting career.
Emma Stone

Birth name: Emily Jean Stone
Actress Emma Stone was actually born Emily Jean Stone. However, she found that another actor with the name Emily Stone had already registered in the Screen Actors Guild. She tried another stage name briefly, but eventually settled on Emma Stone. Stone has said the change was merely practical and not created as a new identity.
Snoop Dogg

Birth name: Calvin Cordozar Broadus Jr.
Long before Snoop Dogg was a household name, his mother nicknamed him Snoopy as a child because he was like the cartoon character. Born Calvin Cordozar Broadus Jr., he later decided on a professional name by flipping Snoopy into Snoop Dogg. Snoop made a name for himself in the 1990s working alongside Dr. Dre.
Miley Cyrus

Birth name: Destiny Hope Cyrus
Destiny Hope Cyrus was born with a name her parents intentionally picked out with her future in mind. She was a happy kid who went by the nickname Smiley. As she grew older, Smiley became shortened to Miley. Today she goes by her legally changed name Miley Ray Cyrus. These days you’ll hear almost no one refer to her as anything besides her childhood nickname.
Natalie Portman

Birth name: Neta-Lee Hershlag
Neta-lee Hershlag was born in Jerusalem and then moved to the United States with her family not too long after. She went by Portman, her paternal grandmother’s maiden name. The actress says she began using it professionally as a way to separate herself from her personal life when she started acting as a child.
Michael Keaton

Birth name: Michael John Douglas
The Batman/Beetlejuice actor was born Michael John Douglas. When he started his career in entertainment, there was already another actor by that name. He decided to use Keaton, his mother’s maiden name, as his professional surname. This helped him have a different identity in Hollywood.
Lana Del Rey

Birth name: Elizabeth Woolridge Grant
Before she was Lana Del Ray, she was known to use her given name Elizabeth. After a few years of performing under her name and variations of it, she decided to change it. Shortly after adopting Lana Del Ray as her stage name, she gained major recognition for her hit Video Games in 2011.
Rihanna

Full name: Robyn Rihanna Fenty
You might be surprised to know that Rihanna is actually the singer’s middle name.
