It has been almost three years since Ariana Grande released her sixth studio album, "Positions," and fans are already begging her to get back in the recording studio.

The singer/actress just gave her fans some great news: she is almost done filming "Wicked," that the film adaptation she is working on right now,

"Savoring every millisecond left with my Galinda (although she'll be with me irrevocably, forever)," Grande wrote in an Instagram post.

The post shows a picture of the singer standing beneath a rainbow. The post continues, "She shows me so many new things every day."

"I am so grateful, I don't know what to do or say... to be here in Oz where every day is a life-changing one... to be feeling, learning, and growing so much at such a disarming speed... to feel so much love around me, to begin each day before the sun is up and to end after it sets."

The Grammy-Awarded singer will play Glinda the Good Witch, opposite Cynthia Erivo's Elphaba in Jon M. Chu's film adaptation of the iconic Broadway musical.

"To hold my brilliant twin flame/sister Cynthia [Erivo]'s beautiful, green hands every day... to work in the safest, most beautiful and loving, biggest-yet-most-intimate/tiny-feeling spaces... to be lead by the most thoughtful, brilliant, compassionate and warmest possible director on this planet, my other Ozian best friend ever Jon... to be transforming and healing parts of me that I never knew needed it. or maybe did."

Grande concluded her lengthy Instagram post by thanking the cast and crew, as well as reflecting on her time on set.

"I hope this isn't all a dream because as present as I am attempting to be, it sure does feel like one," she wrote. "Happy halfway to this most beautiful crew. my fellow Ozians. my heart will be stuck here forever."

Welcome to Oz

This is not the first time the "pov" singer professed her adoration and love for Erivo and the entire "Wicked" cast and crew.

The first time Grande shared "Wicked" news with her fans, she was in tears-it was the first time she found out that she was cast to play Glinda the Good Witch.

Her older brother Frankie Grande dished out on what the singer went through prior to getting the role: "She worked very, very, very, very, very hard on the audition process and she would let me in afterward and tell me how each one of them went,

"I remember when she told me that she booked it, we just both burst into tears together. Because it was something that she had been dreaming of her entire life."

'Wicked'

According to reports, the film adaptation was based on the Broadway musical, which is also based on the 1995 novel "Wicked: The Life and Times of the Wicked Witch of the West" by Gregory Maguire.

The forthcoming movie is directed by Chu, and will be split into two movies: "As we prepared this production over the last year, it became increasingly clear that it would be impossible to wrestle the story of Wicked into a single film without doing some real damage to it."

"As we tried to cut songs or trim characters, those decisions began to feel like fatal compromises to the source material that has entertained us all for so many years."
