Lady GagaandBradley Cooper‘s performance ofA Star Is Born‘s signature tune “Shallow” atSunday’s Oscarsmay have delighted fans watching at home, but the electrifying chemistry between the two stars leftMel Bunsettled.

The Spice Girls singer, 43, criticized Gaga and Cooper duringGood Morning Britain‘s Academy Awards telecast, explaining that she couldn’t help but think about Cooper’s girlfriend, Irina Shayk, the whole time.

Agreeing that the duo had “the look of love,” Mel B hoped that the energy between Cooper and Gaga — who recentlysplit from fiancé Christian Carino, her rep confirmed to PEOPLE exclusively on Tuesday — was just for show.

“I would like to think it was part of the whole performance, because there’s a women’s code and hopefully that’s not… hopefully it’s only professional,” she said.

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!”

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 huggedShaykwhen he got back to his seat, and the model congratulated Gaga, whom Shayk cheered on throughout the night.
