Emma Stone, Katy Perry, Bruno Mars, Nicolas Cage: Hollywood stars who changed their names and built unforgettable identities

In the ever-evolving world of showbiz, a name is more than just a label—it’s a brand. While some stars change their names for a fresh start, others are forced into it by industry rules or a desire to step out of a famous family’s shadow. Many stars swapped their birth names for ones that felt punchier, easier to remember, or simply more marketable as they chased the spotlight. Below are six celebs, who changed their original names to build a new persona.

Born Katheryn Elizabeth Hudson, she shared a surname with actress Kate Hudson, sparking confusion early on. Her mom suggested Katy Perry, borrowing her late mother’s maiden name for a clean slate. This shift fueled her breakout with “I Kissed a Girl,” turning her into a candy-colored pop icon who owns her bold persona.

Born as Emily Stone, she faced a snag at 16: another Emily Stone was already registered with SAG-AFTRA, the actors’ union. She briefly tried Riley Stone but settled on Emma, a nod to her middle name that felt close enough to home. This propelled her through “Superbad” to Oscar glory in “La La Land,” proving the switch sparked her quirky charm.

Caryn Elaine Johnson wanted a name that popped during her comedy rise. She chose Whoopi for her gassy childhood pranks and Goldberg to claim Jewish roots, blending humor with heritage. The moniker lit up “The Color Purple” and her EGOT wins, making her a trailblazing force in comedy and talk shows.

Born as Mark Sinclair, Vin Diesel shed his real name for Vin Diesel, shortening Vincent from his middle name and Diesel from friends’ nicknames for his relentless hustle. This gritty alias fit his action-hero vibe in “The Fast and the Furious” franchise, where he revved up a global empire of muscle cars and family loyalty.

Nicolas Coppola ditched his famous uncle Francis Ford Coppola’s name to forge his own path. Inspired by composer John Cage and Luke Cage comics, he became Nicolas Cage. The eccentric choice unlocked wild roles in “Leaving Las Vegas” and “Face/Off,” cementing his status as Hollywood’s ultimate oddball genius.

​ Born Peter Gene Hernandez, he grew up in Hawaii with a family full of musicians. He picked Bruno Mars to honor his Italian heritage through his father’s side and add a funky, planetary vibe that matched his upbeat pop-soul sound. The name stuck when he signed his first deals, helping him blast onto charts with hits like “Just the Way You Are.” Today, Bruno Mars embodies that vibrant energy on stage​
