Oscars 2019: Lady Gaga and Bradley Cooper's performance described as 'close and intimate' on Twitter

The pair's duet of 'Shallow' received a standing ovation

Lady Gaga and Bradley Cooper‘s "close and intimate" performance at the 2019 Oscars has sparked a huge reaction on social media.

During the awards ceremony, Gaga and Cooper sang a moving duet of the song ‘Shallow‘ from their film A Star Is Born, receiving a standing ovation from the star-studded audience.

The song won Best Original Song, earning Gaga her first Academy Award alongside co-writer Mark Ronson.

Near the end of the performance at the Dolby Theatre in Los Angeles, Cooper joined Gaga at the piano, their heads resting together as they sang the last few notes.

While some have admired Gaga and Cooper’s close relationship, others have said how close they appeared during the duet.

“Isn’t Bradley Cooper in a relationship? Kind of weird how close and intimate he was getting with Lady Gaga,” one person wrote on Twitter.

“I’m still sitting here thinking about how close Lady Gaga and Bradley Cooper’s faces were at that piano,” another added.

Spice Girl Mel B told Piers Morgan and Susanna Reid on Good Morning Britain that she hoped their closeness was “part of the acting of the song”.

Many people have defended the performance.

“I honestly don’t think @ladygaga and Bradley Cooper are secretly together. I just think if you are in her circle she loves you with that much intensity,” one person tweeted.

“It was an act on the stage, like they did on the film. Very dangerous to assume they are anything other than good friends,” another wrote.
