The actors, who star in the upcoming movie Captain Marvel, parodied the intimate performance by the A Star is Born duo at this year’s Academy Awards.
The moment was aired during the first episode of the new series of ITV chat show (March 2), prompting an applause by the audience and exclaims of “wow” by host Ross.
Larson and Jackson’s recreation of the duet comes after Gaga addressed her Oscars performance with Cooper, in which speculation grew that the pair are more than friends.
Speaking on Jimmy Kimmel Live! earlier this week, Gaga said: “First of all, social media, quite frankly, is the toilet of the internet. And what it has done to pop culture is abysmal.
“This is a love song… the movie – it’s a love story. We worked so hard, we worked all week on that performance.”
She added: “Look, I’ve had my arms wrapped around Tony Bennett for three years touring the world. When you’re singing love songs, that’s what you want people to feel.”
Gaga and Cooper won an Oscar for Best Original Song for ‘Shallow’ at the awards ceremony in February.
