MIKAEL JANSSON for Interview

UPDATE (11/1): Well there's no surprise here! According to TVLine's sources, Millie Bobby Brown is returning to Stranger Things for season two. The actress will also be reportedly bumped up to series regular.

Original Story (10/25): Lots of us had our first kiss in the back of the school bus, during recess underneath the swings or at a kid's birthday party. But Millie Bobby Brown's experience was a little less intimate. The the 12-year-old Stranger Things actress has gone into detail about her first kiss being none other than co-star Finn Wolfhard.

When friend/Sia muse Maddie Ziegler (who chatted with her for Interview magazine) asked about the kiss, Brown said:

"You're an evil, evil person. You know that? Are you aware of that, Maddie? 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. But then, like, when I'd done it, I thought, 'Wow. It makes sense for the storyline.'"

The talented girls' adorable conversation also included tidbits on Brown's guest role on Grey's Anatomy and her thoughts on people dressing up as Eleven for Halloween. "At Comic-Con, people dress up as her. It's very rewarding in a way, and as strange as Stranger Things. People are embracing her character and trying to portray her," Bown said.

"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," she continued while comparing it to Ziegler's character in Sia's "Chandelier" video.

Brown also touched on how playing Eleven is different from her other roles, because she rarely speaks:

“I had to play a man in one of my shows, and kill my mum in one of my shows, so it’s very weird the things I bump into. And in this show, 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.”

On Monday, Brown seemingly teased the return of Eleven in Season 2 of Stranger Things, posting an Instagram photo of her and David Harbour. “Shhhhh @dkharbour don’t say a word! #s02 #strangerthings @netflix @strangerthingstv," the caption read.
