Millie Bobby Brown Just Said the Sweetest Thing About Sadie Sink’s Performance in the “All Too Well” Short Film

Since she landed her breakout role as Eleven on Stranger Things in 2016, Millie Bobby Brown has gone on to become one of the world's biggest stars. From founding her clean beauty brand, Florence by Mills, to producing and starring in multiple Netflix projects like Enola Holmes, she's proven to be a well-rounded talent. She's even dipped her toes in the fashion industry thanks to collaborations with Converse, Vogue Eyewear, and Pandora.

Ahead of her 18th birthday on February 19, Millie is proving there is nothing she can't do with a ton of new projects like Stranger Things 4 and Florence by Mills' latest Color in Wonderland collection. I caught up with Millie on a Zoom call, where we had a "bestie chat" all about the inspo behind Florence's latest drop, her favorite Olivia Rodrigo song, and of course, her reunion with the Enola Holmes cast.

In the past, Florence's product drops have honed in on the classic "no-makeup makeup" vibes, but Color in Wonderland introduces new lip products to inspire people to step out of their comfort zones. Through her funky outfits and super cute manis, Millie has been all about expressing herself through color, and that sentiment shines through with her brand's latest drop. "I've been so excited for this collection to come out [because] it represents color, boldness, and not being afraid to create looks to match with your moods and who you are as a person," Millie explained.

Millie also teased what fans can expect from the brand later this year. "We've always been focused on beauty and skincare, but we branched out to haircare, and now we're branching out to something else in late fall, which is so exciting and also ever-evolving."

Her beloved character, Enola Holmes, is also evolving into a "more mature, hectic, and loud" version of herself in the film's sequel, which is slated to release on Netflix this year. After filming the first movie and becoming fast friends with her co-stars Louis Partridge and Henry Cavill, Millie said that their reunion was incredible as they're super fun to work with. One of her favorite memories was bringing her pup, Winnie, and her bunny to set, where they'd run around and play with the cast and crew. "I would be in my Enola gowns, which are huge and seven layers of fabric, and I'd have my dog and my rabbit in my hands," Millie laughed. "I looked insane, but I was like, 'I'm a mum. Before anything, I'm an animal mum.'"

While fans will have to wait to see how Eleven's journey continues in the fourth season of Netflix's Stranger Things, we can hold onto the fact that Millie gushed about her co-star, Sadie Sink. "The 10-minute version of 'All Too Well' changed my life. The film? Sadie? I just sat there and cried, practically," she shared. After bonding with Millie over Taylor Swift and Olivia Rodrigo — her favorite SOUR track is "1 Step Forward 3 Steps Back," BTW — I naturally had to ask her if she'd ever follow in Sadie's footsteps to star in a music video for Olivia.

"I'm just gonna let Olivia do her thing and I'm gonna sit back, I have so much fun watching her videos and listening to her music. I don't really involve myself because I know that she's just too brilliant," Millie said before sharing that the SOUR vinyl was on heavy rotation as one of her Christmas gifts. "I love '1 Step Forward 3 Steps Back.' It makes me wanna cry every time. I think my boyfriend's gonna kill me if I listen to it around him anymore."

With all her on-screen and behind-the-scenes projects aside, Millie has a big year ahead as she's hitting a milestone and turning 18. "I feel like 18 doesn't really mean I'm an adult. Like, I don't think I'm ever gonna be an adult," she explained. "I heavily rely on my family for everything I do. A good life lesson I've learned is to just be grateful and understand where you came from, to always help others, and to keep creating things that make people happy. My biggest thing is just constantly promoting positivity and making people smile."
