Millie Bobby Brown underwent a blonde transformation, over the weekend, as she celebrated her 18th birthday with boyfriend Jake Bongiovi - with the pair channelling Barbie and Ken.
The actor - who is best known for playing Eleven in Stranger Things - posted about her birthday makeover on Instagram yesterday, ahead of celebrating the milestone in London.
The teenager shared photos of herself with her 47.6 million followers on the platform, in which she wasn't sporting her usual brunette hair - instead seen platinum blonde.
She posed alongside boyfriend Jake, 19, whilst wearing a vintage corset gown, which she referred to as the "goddess dress." And two additional snaps showed her standing alone.
Teasing that the look was inspired by the iconic doll Barbie, she wrote in the caption of the post: "Hey Ken!" She tagged her make-up artist, hairstylist and designer in the post.
And in his own post, Jake - who is the son of singer Jon Bon Jovi, 59 - also referenced the fashion doll alongside the couple's photo, with him writing: "Happy birthday Barbie ily."
The couple and some friends are said to have visited the Cirque le Soir nightclub in London yesterday evening, before moving on to the Windmill Club, according to the Daily Mail.
The birthday celebrations come after the release date for the new season of Stranger Things was announced earlier this week. The fourth season will be split into two parts.
The science-fiction drama, which premiered on Netflix in 2016, follows a group of friends investigating supernatural events in their town - with the series set during the 1980s.
Millie stars as a mysterious young girl with psychokinetic abilities, who is known as Eleven. Other cast members include Winona Ryder, 50, and David Harbour, 46.
It was revealed this week that the upcoming fourth season will be split into two parts with Volume 1 set to be released on May 27. The second volume will be released on July 1.
The show's creators - twins Matt Duffer and Ross Duffer, 38 - issued an open letter to fans in which they announced that the new season has an "unprecedented length."
They said that it included nine scripts, almost two years of filmings, thousands of visual effects shots and a runtime that is "nearly twice the length of any previous season."
The pair - known as the Duffer Brothers - also revealed that the fifth season will be its last, with them having planned out "the complete story arc" for the show seven years ago.

They said it has "proved too large" to tell in four seasons, so the upcoming instalment will be its penultimate season - with the show concluding with season five.
However, they promised that there are "still many more exciting stories to tell within the world of Stranger Things: new mysteries, new adventures, new unexpected heroes."
Stranger Things returns on Netflix for Volume 1 of its fourth season on May 27. The second volume will be out on July 1.
