Even though my nationality is Chilean, I grew up Italian. So when people say to me, 'What's your nationality?' I say, 'I'm Chilean, but I grew up Italian.' I feel like I'm both."
She was raised in Marlboro, New York.
6.Dylan and Cole Sprouse were born in Arezzo, Italy on August 4, 1992. At the time, their American parents were teachers at what Cole described as a "school slash cult" in Tuscany.

He told Ability magazine, "I only remember glimpses of it. I've been back to Heidelberg since, and it's very strange seeing the buildings and recognizing them, or being able to go down the street, saying something like, 'We're going to turn here, and there's a grocery store.' It's funny that this place feels somewhat familiar and yet so foreign at the same time."
After his family moved back to the US, he grew up in northern Virginia.
9.Pedro Pascal was born in Santiago, Chile on April 2, 1975. His father, a fertility doctor, and his mother, a child psychologist, fled the country with their children and sought political asylum when Pedro was 9 months old.

When Sebastian was 12, his mom married an American headmaster, so they moved to Rockland County, New York.
He told Broadway.com, "When you're thrown into something so young, you don't think about it too much. I was an only child, so it took me a while to form friends because my stepdad was the headmaster, and I had an accent for a while, but it was still early, and you just sort of suck in everything at that age."
12.Rose McGowan was born in Florence, Italy on September 5, 1973. Her American parents were part of the Italian chapter of the Children of God, a polygamous cult.
When Rose was 9, her father escaped the cult with one of his two wives and all three of his children.
She told People, "I remember running through a cornfield in thunder and lightning, holding my dad's hand and running as fast as I could to keep up with him. We hid in an old stone house and had to boil pots of hot water to take baths. [The cult] sent people to find us. I remember a man trying to break in with a hammer."
Eventually, they landed in Colorado. After a while, Rose's mom, who had stayed in Italy longer, moved to Oregon, so Rose was sent to live with her.
However, at 13, she ran away from home because of her "mean stepdad," but after experiencing homelessness for a year, she reunited with her father and moved in with him in Washington.

She told Elle, "My parents would dress us up in traditional Vietnamese clothing to go to school for heritage day. We have a Vietnamese nanny that my parents wanted [my brother and I] to have so we could stay in touch and know where we came from. They tried to have us eat Vietnamese food. Now, I love it... My parents tried their best to educate us on where we came from. The way that I grew up was that your experience is your experience. I think there's a misconception that all Asian American experiences are the same. My experiences with my family and the way they wanted me to know my culture are not the same as others."
Because of her dad's job, they moved around, so she lived on an island in Washington, in New York, and in Los Angeles.
14.Mischa Barton was born to an Irish mom and an English dad in London, England on January 24, 1986. When she was 5, they moved to New York because of her dad's work.
She told Hello, "People assume I'm from Orange County. Marissa [Cooper, her character on The O.C.] hasn't seen much outside her bubble, but I like people to discern that I'm an English-Irish girl who grew up in New York and moved around a lot with her dad's job."
15.13 Reasons Why actor Ross Butler was born to a Chinese Malaysian mom and an English Dutch dad in Singapore on May 17, 1990. He moved to the US at 4.
His mother raised him as a single parent in Fairfax, Virginia.
He told Mochi magazine, "I grew up around American kids, and I'm an American. I was raised in this culture. Telling that story isn't that hard. My mom brought her background of academic strictness, but that didn't define who I was. It's an attribute just like all white Americans have their own unique attributes. Growing up, I wish I had seen the stories I saw, just with Asian characters. I wish there was an Asian version of Tom Hanks, or an Asian American version of Ryan Gosling."
At 20, he moved to California, and at 21, he began pursuing acting.

When she moved, she worked hard to lose her British accent, which she later somewhat regretted as an adult.
On The Kelly Clarkson Show, she said, "Everyone made fun of me 'cause it's such a formidable age at the age of, like, 5 or 6 when they're like, 'Wait, you can't say your Rs?' And so I used to watch movies to replicate accents."
