"My first American cover! And it's Interview magazine! Ahhhhhh!" the Spanish-born, British actress gushed over Instagram on Tuesday. "#interviewmagazine #karltemper."

In the accompanying feature, Brown, who portrays Eleven on the hit Netflix series, was interviewed by her new best friend, 14-year-old dancer Maddie Ziegler. The two adorably revealed how their friendship came to be. According to Ziegler, they "clicked right away."

"I got tickets to go see So You Think You Can Dance because I've been watching you since I was about 7, and I was crazy when I knew you were actually going to be on the show," Brown said of being starstruck by the former Dance Moms diva. "And the whole show I was looking at you like, 'Please let her look at me.'"

"Then they told me that I could go backstage and meet you, and I’m literally, like, taking deep breaths, like, 'Oh my goodness,'" she continued. "And then you were a normal human being. You were Maddie Ziegler. Then you followed me on Twitter -- and I had a meltdown -- and the rest is history, really."

And because Ziegler is one of Brown's closest pals, she had no shame in asking Brown about her first kiss, which just so happened to be onscreen with her costar, Finn Wolfhard (Mike Wheeler).

"You're an evil, evil person. You know that? Are you aware of that, Maddie?" Brown joked. "Yeah, I did have to kiss Finn. At the end of the day, it's only acting, and it's something you have to do, and I would do anything for the show. I cut my hair, I kissed Finn. It was definitely strange."

"It was, like, my first kiss, so it was kind of weird," she added. "But then, like, when I'd done it, I thought, 'Wow. It makes sense for the storyline.' Finn reacted quite well and I didn't. I felt really bad afterwards."

One thing she doesn't feel bad about, however, is all the hype surrounding her badass character. Brown says she's stoked Eleven is being dubbed as one of the most popular Halloween costumes this year.

"It's very rewarding in a way, and as strange as Stranger Things," she explained. "People are embracing her character and trying to portray her. I think it's nice to see what different people think of her character. I'm cool with people dressing up as Eleven for Halloween. I definitely want to open my door and give them candy."

Brown also admitted that portraying the "super creepy" and mysterious role of Eleven didn't come easy, despite the fact that she's been acting since she was nine years old. "It was different from [my previous] roles because in those I had to speak a lot," she said. "I had, like, paragraphs."

"In this show," she continued, "I realized I didn't have to speak with my mouth, I had to speak with my face. Instead of actually saying, 'I'm angry, I'm sad, I'm confused,' I had to do it with my face, and that was challenging. But I really enjoy playing a challenging role. I love playing Eleven."

Although Brown loves being on set with her boy-heavy Stranger Things family, she revealed one of the reasons why she's so grateful for Ziegler's friendship is because they get to "talk about normal things a girl would talk about."

"I am [basically] the only girl [on set], and the boys have their squads," Brown dished of working with Wolfhard, Gaten Matarazzo and Caleb McLaughlin. "They have their group, and it's definitely difficult because they're boys and talk about boy stuff. They talk about girls and video games."

"They're like my big brothers," she added. "They annoy me, but we are very, very close."
