Joe Keery is "a bit of a nerd"

Asked what people would be surprised to realise about him, he told America's ELLE magazine: "That I'm a bit of a nerd, deep down. I was a nerdy theatre kid, making movies with my friends.

"On tour earlier this year, my friends and I were hanging with some of the crew from the other band, and one of the young ladies said, 'Wow, you guys are not how I expected you to be.'

"And I think it was because we were just being silly. And kind of nerdy."

When it comes to what he finds attractive in the opposite sex, Joe looks for a sense of humour.

Asked what makes him go weak at the knees, he said: "When someone's funny. When somebody's quick-witted and you have that immediate back-and-forth going on-that to me is like, Yep, here we go."

The End of Beginning hitmaker, who releases music under the alias Djo, believes it is important to "own" when people are wrong in relationships.

He said: "I had a friend reach out for advice for this dilemma. And I feel like, you've just gotta be real clean and honest with it-really upfront-especially if you're in the wrong. You just gotta own it.

"Also, [buying them] a little something might help. Maybe you're getting someone flowers, or you're taking them to a place they like to go. Just taking the knee for the other person and saying, 'I messed up. I'm so sorry.' "

Meanwhile, although Joe was initially "incredibly intimidated" by his Stranger Things co-star Winona Ryder, he is very grateful for her friendship because she has so much knowledge to share.

Discussing which woman he has learned most from, he said: "I got a lot of great women in my life, obviously my family, but the first person who comes to mind is Winona Ryder. I was incredibly intimidated at first because I grew up on her movies. But as I got to know her, I learned how invested and passionate she is about work.

"She really knows her stuff - loves music and film, maybe more than anyone else in my life. I'll get a random text, like, 'Here's an isolated Marvin Gaye vocal track from the stems that they never used from this song.' The deepest cuts.

"She's like an encyclopedia, and she's eager to share. She's been to a million shows. It's cool to have someone who's just really excited by all of this."
