Two new duets will appear on the soundtrack for Judy, the upcoming Judy Garland biopic, and we're officially over the rainbow.

Decca and Republic Records have announced that Oscar winner Renée Zellweger, who stars as the late Hollywood legend, recorded the duets with queer music icons Sam Smith and Rufus Wainwright, Rolling Stone reports.

Zellweger teams up with Smith on "Get Happy," one of Garland's most beloved songs, which she originally sang in the 1950 film Summer Stock. Wainwright joins Zellweger for a fresh rendition of the holiday classic "Have Yourself a Merry Little Christmas," which Garland famously sang in the 1944 film Meet Me in St. Louis.

“When I was 17 years old I did a project on Judy Garland for my Film Studies A-Level," says Smith in a statement. "I was immediately immersed into the magic of Judy and her incredibly brave and triumphant story. She has remained as one of the icons of my life. She was one of the bravest humans out there and her vulnerability and honesty in her art still gives me goose bumps like it did the first time. It was truly an honour to sing with Renée. Nobody could have played Judy as well as Renée, and it is a career highlight for me to be singing with her, and in some small way, with Judy. I hope everyone loves the film as much as I did."

“Judy Garland has been a constant force in my life," adds Wainwright, who earned a Grammy nomination for his live album Rufus Does Judy at Carnegie Hall. "The Wizard of Oz was one of the pyramids of culture that I gazed at as a small child. It’s nice to come back and observe her again in the film and through this wonderful duet with Renée, her performance is astounding in a film that focuses on the love and the generosity that Judy always had for the world around her. It reminds me of how unique her life and art were."

Other Garland songs featured on the soundtrack, all sung by Zellweger, include “The Trolley Song,” “The Man That Got Away,” and “Come Rain or Come Shine.” The album's first single, “Over the Rainbow,” is available now.

Judy doesn’t chronicle Garland’s entire life like the classic TV movie Life With Judy Garland: Me and My Shadows, instead focusing on the final months of her life as she readies for a sold-out London concert run in the late '60s. The film is based on Peter Quilter’s play End of the Rainbow, adapted for the screen by The Crown writer Tom Edge and directed by Rupert Goold.

“As she prepares for the show, battles with management, charms musicians, and reminisces with friends and adoring fans, her wit and warmth shine through,” reads an official synopsis. “And yet Judy is fragile. After working for 45 of her 47 years, she is exhausted; haunted by memories of a childhood lost to Hollywood; gripped by a desire to be back home with her kids. Will she have the strength to go on?”

Zellweger recently made a surprise appearance at London Pride, where she debuted the Judy trailer and gave a passionate speech about the LGBTQ community.

"Can I just take a second for appreciation and acknowledgement of the courage and the suffering and the struggle of all of those over the last 50-plus years in the fight for what we all know are fundamental human rights," the What/If star told the crowd. "God bless them, and God bless every one of you here today! Can I get an 'Amen!'"

Both Judy and its soundtrack are out September 27.
