Ariana Grande posted a heartwarming childhood throwback of herself dressed as Dorothy Gale from The Wizard Of Oz.

The 30-year-old is starring in a two-part movie adaptation of Wicked, the hit Broadway musical about Dorothy’s nemesis, The Wicked Witch Of The West.

In the upcoming films, Ariana plays Glinda The Good Witch Of The North, one of the fan favorite characters from The Wizard Of Oz.

She promoted the project with an Instagram album Thursday, filled mostly with recent pictures of her and her co-star Cynthia Erivo working on Wicked.

But she concluded the post with a charming snap of herself as a little girl posing sweetly in her Dorothy outfit in front of a Christmas tree.

Based on the 1900 novel The Wonderful Wizard Of Oz by L. Frank Baum, the 1930s movie has become an enduring children’s classic.

The Broadway musical Wicked, meanwhile, was based on a novel of the same name by Gregory Maguire telling the backstory of The Wizard Of Oz’ villain.

Cynthia stars in the screen adaptation as Elphaba, a green-skinned girl with magical powers who later becomes The Wicked Witch Of The West.

Ariana features as the spoiled, popular Galinda, who becomes Elphaba’s best friend – and later her grudging rival, rechristened Glinda.

The movies were plunged into scandal when it emerged Ariana was having an affair with her married castmate Ethan Slater, who has now left his wife Lilly Jay.

However Ariana’s new album of behind-the-scenes photos sidestepped Ethan entirely, focusing instead on her collaboration with Cynthia.

She wrote glowingly in her caption: ‘@wickedmovie see you in november i am so grateful, words don’t suffice,’ adding: ‘i love you forever, so much @cynthiaerivo’.

Ariana included multiple pictures of her and Cynthia in costume, including one of them embracing for a scene while taking direction from Jon M. Chu

Other photos depicted the two leading ladies enjoying their downtime between takes, checking their phones or lounging in director’s chairs

One of the images was a blurry candid selfie of an exhausted Ariana falling back onto a sofa and yawning, apparently still in a Glinda outfit

She also adorably revealed that she and Cynthia acquired iced beverage cups with straws matching their characters – green for Elphaba, pink for Glinda

Although the album was dominated by her friendship with Cynthia, Ariana also featured a picture of herself with her hair and makeup artist Gabor Kerekes

Part one of the Wicked movie is slated for release this year on November 24, with the follow-up to arrive about a year later on November 26, 2025

Ariana’s co-stars include Jeff Goldblum as The Wizard Of Oz and Jonathan Bailey as Fiyero, Glinda and Elphaba’s mutual love interest
