Zoe Saldana sobs after winning her first Golden Globe Award in plunging YSL gown

Zoe Saldaña cried tears of joy upon winning her first Golden Globe Award for best supporting actress in a motion picture (musical/comedy) during the 82nd ceremony, which was held at the Beverly Hilton in Beverly Hills on Sunday.

The 46-year-old action star - best known for blockbuster franchises Avatar, Guardians of the Galaxy, and Star Trek - was finally recognized for her serious dramatic work as a transgender Mexican cartel leader's attorney Rita Moro Castro in Emilia Pérez.

'I have dyslexia and I tend to forget when I'm really anxious. I'm filled with adrenaline, but my heart is full of gratitude,' Zoe (born Zoë Yadira Saldaña Nazario) began her emotional two-minute speech.

'Thank you so much to the Golden Globes for celebrating our film and honoring the women of Emilia Pérez. Thank you so much!'

Saldaña managed to win over her own castmate Selena Gomez as well as Wicked's Ariana Grande, The Brutalist's Felicity Jones, The Substance star Margaret Qualley, and Conclave's Isabella Rossellini whom she called 'magic.'

'Selena, I am sharing this with you,' the half-Dominican, half-Puerto Rican triple threat gushed onstage. 

'I know that it is a competition but all that I have witnessed is just us showing up for each other and celebrating each other, it's just so beautiful.'

Zoe also singled out her castmate Karla Sofía Gascón, who had just lost the best actress trophy to The Substance star Demi Moore: 'No one other than you could have played Emilia Pérez. No one. Reina (queen)!'

After thanking the cast and crew, Saldaña rushed to thank her close ones as she was being played off: 'My mom [Asalia] is here! My sisters, my husband, and my sons - I love you. I love you. You guys are everything, thank you!'

And while the Lioness producer-star's husband of 11 years - The Absence of Eden filmmaker Marco Perego Saldaña - wasn't there, he proudly reposted her speech via Instastory.

Zoe's biggest number in Netflix's Spanish-language musical - El Mal - wound up winning best original song at the Globes.

Saldaña headed up to the stage for a second time to support composers Camille and Clément Ducol as they accepted the trophy, telling her: 'Zoe, you just shaked the house and shaked our souls.'

The former ballerina got to go onstage for a third time with the rest of the cast and crew when Emilia Pérez was awarded best motion picture (musical/comedy).

'The light always wins over darkness,' Karla said of transgender rights.

'I have a lot of things to say to you because you can maybe put us in jail, you can beat us up, but you never can take away our soul, our resistance, or our identity. And I want to say to you, raise your voice and say, "I am who I am, not who you want."' 

French filmmaker Jacques Audiard's critically-acclaimed queer movie also took home the trophy for best non-English language motion picture - but it lost the prizes for director, screenplay, and score.

For the red carpet, Zoe took the plunge in a black-sequin Saint Laurent by Anthony Vaccarello dress, matching Saint Laurent heels, and Cartier jewelry selected by stylist Petra Flannery.

Hairstylist Mara Roszak gave Saldaña a 'modern knotted updo' and make-up artist Vera Steimberg brought out her natural beauty for the HD cameras.

The Meet Me in Rome producer will next voice Aunt Olga in Pixar's animated alien abduction comedy Elio - hitting US/UK theaters on June 13 - alongside Brad Garrett, Jameela Jamil, and Shirley Henderson.

Zoe will also reprise her motion-capture role as Neytiri in James Cameron's $250M-budget three-quel Avatar: Fire and Ash - hitting US/UK theaters December 19 - alongside Sam Worthington, Sigourney Weaver, and Stephen Lang.
