Millie Bobby Brown and David Harbour's next project is coming "sooner than expected".

The former Stranger Things co-stars, who played Eleven and Jim Hopper in the hit Netflix sci-fi show, are continuing to work together and Millie has given a major update on their future plans.

She told the Happy Sad Confused podcast: "The David Harbour project is sooner than expected. "And it's David's idea, so kudos to him."

Millie added that plans for a future project are "concrete", and gave a hint of what to expect when she was asked for more details.

She teased: "Father-daughter is where we live, but Netflix will always be our home."

The 22-year-old star noted that generally she's "slowly developing things with Netflix, my home studio", which includes her upcoming rom-com Just Picture It with Gabriel LaBelle.

Meanwhile, her planned TV series Prism might be on hold for now, as Millie is trying to figure out her "time" and "schedule".

Millie and David, 50, were the subject of much speculation during the fifth and final season of Stranger Things, after reports she filed a harassment and bullying complaint against him ahead of production for season five.

He recently told Variety the report was a "weird thing" which "came out in a weird way", and added: "Straight up, Millie and I are working on several …

"You'll see more of me and Millie -- 10 years wasn't enough.

"There is a special bond there. I love her. She loves me."

David insisted it is normal to get involved in "arguments and disagreements" with colleagues who have had a close working relationship for so long.

He added that they found it easy to resolve their differences once there were no other people involved.

He explained: "It's simple. It was just a simple rupture-and-repair thing that, once we cleared everybody out of the way and talked to each other, we're fine.

"Everyone nowadays is very scared of talking about things. People are very scared of being human. It's unfortunate, because I don't know how to navigate this weird media world.

"But it was completely normal, and we adore each other and always have."

And Millie insisted she has a "lot of gratitude" for David and their time working on the show as Eleven and Jim Hopper respectively.

She told Variety in an email: "Obviously I changed so much from Season 1 to Season 5, and David was there through all of it.

"Over time, our relationship became much more collaborative creatively. When you work with someone for that many years, we could really push each other emotionally in scenes.

"Even though the series has ended, there's still a lot of gratitude. Getting to share that experience with him for so many years is something I'll always remember and value."
