One of those users included Esposito, 45, who provided one simple reaction to Gaga’s relationship with her ex-husband, first captured by Comments by Celebs.
Cooper, 44, and Esposito wed in December 2006 but officially called it quits by May 2007, after four months of marriage. Since 2015, the actor has been dating model Irina Shayk.
Gaga, meanwhile, was engaged to Christian Carino for approximately four months before the pair officially ended things, her rep confirmed to PEOPLE exclusively last Tuesday.
Fans have long been enamoured by Gaga and Cooper’s on- and off-screen chemistry, to the point where some online wanted their passionate performance on Sunday to end with a kiss.
Instead, Gaga and Cooper smiled and hugged as they walked off the stage. Their embrace continued backstage as the two were met with a swarm of claps from well-wishing production staff.
“Did I nail it?” asked Gaga. Taking in the congratulations, she 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 the mic-pack attached to the back of her dress — and Cooper and Gaga, side by side, made their way to their seats via the stage.
During the commercial break following their duet, the pair came out arm-in-arm to huge cheers and another standing ovation from the entire house. Cooper kissed and hugged Shayk, 33, when he got back to his seat, and the model congratulated Gaga, whom Shayk cheered on throughout the night.
After “Shallow” won the award for Best Original Song, Gaga also sent love to Cooper in a teary acceptance speech.
“Bradley, there is not a single person on the planet that could’ve sung this song with me but you,” she said. “Thank you for believing in us, thank you so much.”
