Girls night in! Stranger Things star Millie Bobby Brown talks about best friend Maddie Ziegler and the pair's exciting first sleepover

Millie Bobby Brown is already making quite a name for herself, following her rock star performance in the retro-styled Netflix hit Stranger Things.

The 12-year-old sensation got the star treatment while appearing on Ellen Monday.

In the segment, Millie talked about haircuts, awards season and the star's very first sleepover with best-friend Maddie Ziegler.

Guest of honor: Millie Bobby Brown looked cute as can be while making her first appearance on The Ellen Degeneres Show on Monday

Since meeting in July, Millie has become incredibly close with the talented dancer.

'She is my best friend, actually. We’re very, very good friends. We’ve only known each other for about five months now... She’s so inspiring to me,”

Maddie even invited the Stranger Things star to her very first sleepover, although the evening was not without its drama. 

Heart of the matter: The 12-year-old sensation sported a heart-patterned frock with high top sneakers

Millie explained: 'She was like "Do you want to come over?" and I was like "Sure!" So, I go over, and at 3:00 in the morning, the fire alarm comes on. 

'We all had to get rushed out of her apartment building. I’m crying because I’m like "My first sleepover’s ruined!"'

The star concluded the story saying: 'So, yeah, we’ve been through a lot.'

The actress looked poised during her first appearance besides the spunky daytime host. 

Millie wore a chic black and red heart-patterned frock with a pair of high top sneakers on bottom.

She wrapped a thin lace scarf tied into a bow around her neck, layering the look with a thin gold chain. 

The English ingenue rocked a short hairdo, likely in the awkward stages of growing out her shaved head from playing the super powerful character Eleven.

The rising star was careful not to reveal any hair-related spoilers for the show's highly anticipated second season.

When Ellen asked if Millie would be shaving her head again, the young actress played it cool saying:

'I would love to [tell you], but I just shouldn't. I'd love to keep it a surprise. I think it'd be really cool if you watched the show and were like (gasps).'

The newly-minted celeb also discussed her recent SAG nomination.

When asked about the challenged of playing a character who speaks so little, the nominee explained: 'Why talk about your emotions when you can literally do it' 

The preteen joked that at the event, 'I won't even thank my parents... As a rule I'm going to be like "I want to thank all the producers on Ellen team. I wanna thank the audience on Ellen and I definitely want to thank Ellen."'

Lucky lady: At just 12-years-old, Millie is the Screen Actors Guild's youngest nominee this year

It's been a season of firsts for the young star. On Sunday, Millie stunned on the red-carpet for the 74th annual Golden Globes.

The series was nominated for Best Television Series in the Drama category, as well as a nomination in the Best Actress category for co-star Winona Ryder, but didn't take home any awards.
