"I'm taking back what's mine." The women in Hollywood who had to change their names.

Celebrity name changes aren't exactly new. 

We often hear about actors who changed their name for privacy or took up a stage name when they started making it in Hollywood. 

But for Thandiwe Newton, the reason behind her name change came down to a simple spelling mistake.

Speaking to British Vogue this week, the Westworld actress, who was born Melanie Thandiwe Newton, explained that she was incorrectly credited as "Thandie" in her first movie role and has been called the wrong name ever since. 

Now the 48-year-old is setting the record straight. 

"That's my name," she told the publication. "It's always been my name. I'm taking back what's mine."

Newton isn't the first woman in Hollywood to change her name or have it changed for her.

Here's 14 other actresses who have gone by a different name and the reason why.

Nicki Minaj, real name Onika Tanya Maraj.

"One of the first production deals I signed, the guy wanted my name to be Minaj, and I fought him tooth and nail. But he convinced me. I’ve always hated it," she said back in 2012.

She also doesn't like when her family call her by her stage name. 

"My rule is, whatever you were calling me four years ago is what you should be calling me now, because I don’t like it when my family or close friends call me Nicki Minaj. To me I’m not Nicki Minaj when I’m with them."

Kat Dennings, real name Katherine Victoria Litwack.

"I didn't want to use my family name because I thought, A, it was a little hideous, and B, I wanted to know when someone really knew me or they didn't," she told Philadelphia magazine.

"It’s a sturdy Polish-Jewish name. I used to be really touchy about it, but I couldn’t care less now."

Winona Ryder, real name Winona Laura Horowitz.

When Winona Horowitz was asked what name she'd like to appear in the credits after appearing in her first film, Mitch Ryder’s album was playing in the background, so she simply went with that.

Lea Michele, real name Lea Michele Sarfati.

"Sarfati. That’s my real last name. I don’t use it a lot because I got ‘Lea So-fatty’, ‘Lea So-farty’ at school," she explained on The Tonight Show with Jay Leno in 2011.

"So when I was little, and I went on my first audition they were like, ‘And may we have your name,’ and I was like, ‘Lea Michele’. And I’ve been Lea Michele ever since."

"It’s Sephardic, which is Spanish/Jew."

Mila Kunis, real name Milena Markovna Kunis.

Mila's parents later let her shorten her name when she started booking her first acting gigs in America.

While Portman worked under her birth name at the beginning of her career, she later decided to change it for privacy reasons.

She chose Portman because it's her paternal grandmother's maiden name.

Gigi Hadid, real name Jelena Noura Hadid.
