Let’s be honest, Hollywood runs on reinvention. Whether it’s a new look, a new role, or, in this case, a brand-new name, stars know that image is everything. Before they hit it big, many of your favorite celebrities were going by names that might’ve never made it past the audition room. From heartfelt tributes to clever rebrands, these stage name transformations tell their own fascinating stories. These are 10 of the biggest shock celebrity name changes, unveiled one by one, like the third act of a film twist.

10. Lily James
Before appearing on our screens as Cinderella or Pamela Anderson, Lily James was known by her birth name, Lily Chloe Ninette Thomson. After her dad, James Thomson, died of cancer, she decided to adopt his first name as her career surname, a stunning and very personal tribute. Not only was it a tribute to her dad, but it also provided her with a name that sounds eraless and naturally chic. It’s one of those little touches that make her Hollywood success all the more genuine.

9. Elton John
It’s difficult to picture anyone referring to Elton John as Reginald Kenneth Dwight, but that was his real name. When he opted to pursue his musical ambitions, he created a new name for himself based on two important figures in his early days, saxophonist Elton Dean and blues musician Long John Baldry. He even included “Hercules” as a middle name to give it that extra element of drama. Elton has claimed that taking on a stage name provided him with a “new lease on life,” enabling him to move beyond painful memories and move into the larger-than-life character we know today.

8. Marilyn Monroe
Before becoming one of Hollywood’s most iconic figures, Marilyn Monroe was named Norma Jeane Mortenson, or Baker, depending on the record. When she signed with 20th Century Fox, a studio boss realized that she would be “Marilyn” since she reminded him of Broadway darling Marilyn Miller. Monroe, which was her mother’s maiden name, filled in the rest. Strangely enough, she legally changed her name to Marilyn Monroe only ten years later, when she was already an international icon of beauty, glamour, and star tragedy.

7. Whoopi Goldberg
Born Caryn Elaine Johnson, Whoopi Goldberg’s name origin is as funny as it is significant. The “Whoopi” portion allegedly originated as a nickname in her youth; she once quipped that it was because she would “let it go” like a whoopee cushion. The “Goldberg” portion originated with her mother, who felt that a Jewish-sounding last name would help her daughter gain more access into show business. The result? A name that’s as unique and as fiery as her personality. And honestly, could anyone else call her anything else?

6. Jamie Foxx
Comedian and actor Eric Marlon Bishop transformed himself early in his stand-up career for a very strategic purpose. On open mic nights, women comedians were frequently summoned first, so he adopted a gender-neutral name, Jamie, to maximize his chances of getting on stage. The last name “Foxx” was his tribute to comedic legend Redd Foxx. The smart decision not only earned him more laughs but also distinguished him in the world of entertainment. Now, Jamie Foxx is a name that is respected in comedy, music, and movies as well.

5. Bruno Mars
Before he was chart-topping and Grammy-winning, Peter Gene Hernandez was a gifted Honolulu kid with a dream and a fear of being stereotyped. When he was starting, he realized people from the industry would assume he sang Latin because of his surname. Determined to break those stereotypes, he chose “Bruno” after a childhood nickname his father gave him, and “Mars” because, as he put it, “I’m out of this world.” It’s a name that perfectly fits his larger-than-life sound and personality.

4. Diane Keaton
Before becoming a Hollywood icon, Diane Hall had to make a practical change for her acting career. When she joined Actors’ Equity Association, she discovered that another actress already shared her name, so she took on her mother’s maiden name, Keaton. In a twist of fate, her breakout role as Annie Hall actually referenced both her actual last name and her actual nickname. It’s a name that now has decades of film heritage, from The Godfather to Something’s Gotta Give.

3. Kirk Douglas
Born Issur Danielovitch, Kirk Douglas had a typical golden age Hollywood problem: his name was deemed “too ethnic” for American audiences. He hesitantly altered it to something shorter and simpler to pronounce. Although later he confessed that sometimes he regretted abandoning his original name, the move served him well in standing out in a highly competitive business. With that new moniker, he constructed a legend that lasted more than six decades, demonstrating that no matter what name he used, talent always found a way to get through.

2. Emma Stone
Before being the Oscar-winning actress we know today, Emily Jean Stone encountered the usual dilemma: there was already an Emily Stone listed in the Screen Actors Guild. She first attempted “Riley Stone” but never felt comfortable with it, settling on “Emma,” which she’d always adored as a child (thanks to Baby Spice, no less). Even though she changed her mind, she’s admitted that she still feels most like Emily deep down, and sometimes doesn’t even correct others when they address her by that name.

1. Reese Witherspoon
Here’s one that even her Friends co-star Jennifer Aniston didn’t see coming. Laura Jeanne Reese Witherspoon uses her middle name professionally, a Southern custom that stuck. The “Reese” is in honor of her mother’s maiden name, making her stage name both personal and classy. When Aniston was told about it in an interview, her expression told the whole story: complete shock. It’s a great reminder that even the best-known names still can have secrets in plain sight.

The next time you notice a name illuminating the silver screen or going viral on the web, keep in mind, it may be more than a title. For most stars, their pseudonym is not only a label but also a tale, a dedication, or even a modest act of personal reinvention. And in an industry founded on deception, sometimes the greatest shock is just what’s on the name tag.
