Eva Longoria learned more about her "Spanish heritage" while shooting her new documentary

The Hollywood star - who has Mexican and Spanish ancestry - told Byrdie: "I'm Mexican American and I always felt at home in Mexico. I knew [the country] and learned even more while doing 'Searching for Mexico'.

"But my dad had always said we were also from Spain. I used to say, 'No, we're not.' Then I took a DNA test, and it was confirmed."

Eva jumped at the chance to film a follow-up series in Spain, and it proved to be hugely informative for the actress.

She said: "When CNN wanted to do the next season, I said, 'We should do Spain because my ancestors are from Spain.' Shooting 'Searching for Spain' was different, though, because I didn't know [the country] as well.

"In this series, you'll see that my questions are genuine and my curiosity is heightened. I was excited to learn more about my Spanish heritage."

Eva loves that she has such a personal connection to the new documentary series.

The movie star said: "Being able to shape the storytelling of the series has been vital because I am the way in for the audience.

"I wanted it to be relevant to my journey and everybody's journey. Everybody can watch the show and relate to someone.

"Authentic storytelling is important because you want stories from those who have lived them. That's been important in my life, in general, not just with this show."

Eva currently splits her time between Mexico and Spain, and the actress previously explained her decision to leave the US.

Eva - who was born in Texas and previously lived in Los Angeles - said on 'The View: Behind the Table' podcast: "I've been in Europe for almost three years.

"I didn't leave because of the political environment. I left because my work took me there."
