After taking in the plaudits for their Oscars performance of "Shallow," Gaga told Cooper, "I'm so f---ing proud of you!"
Having nailed their Oscar night performance of “Shallow,” their nominated song from their nominated film, A Star Is Born — which is up for Best Picture, along with acting nods for each of them — Gaga and Cooper made their way backstage where they hugged tightly as they were met with a swarm of claps from well-wishing production staff.
After taking in the congratulations and asking, “Did I nail it?” Gaga, 32, looked at Cooper and said, “I’m so f—ing proud of you!”
With only a few seconds to get back to their seats, a handler disengaged Gaga from her mic-pack attached to the back of her dress and, side by side, she and Cooper, 44, made their way to their seats via the stage.
The duo stepped right out of their seats in the front row of the Dolby Theatre in Los Angeles to take the stage during Sunday night’s ceremony to perform “Shallow,” which ended up nabbing the award for Best Original Song shortly thereafter, leaving Gaga in tears.

Gaga played the piano during the intimate take on the track and Cooper initially sat on a nearby stool before joining the pop star on the piano bench. They then sang affectionately cheek-to-cheek as the cameras gave a 360-degree look at their performance, which ended with the two staring into each other’s eyes.
Following their performance, Cooper’s girlfriend, Irina Shayk, led the standing ovation while Gaga and Cooper’s chemistry was palpable as they smiled and hugged as they walked off the stage. They came back out arm-in-arm during the following commercial break to huge cheers from the entire house.

Taking the stage once again to co-accept the award for Best Original Song, Gaga said in part during her speech, “Bradley, there is not a single person on the planet that could’ve sang this song with me but you. Thank you for believing in us. Thank you so much.”
Tears still streaming as she walked backstage holding her trophy, the stunned actress and singer said, “I need a drink” before enjoying an entire glass of champagne.
She and her “Shallow” co-winners enjoyed a moment together, taking photos before making their way back to their seats.
