Wow... things are getting interesting.
Neither Gaga nor Cooper have commented on the picture, but the singer did set the record straight about their intimate Oscars performance. She defended the performance to Jimmy Kimmel and tried to squash all the romance rumors.
"Yes people saw love and guess what, that’s what we wanted you to see. This is a love song…The movie, A Star Is Born, is a love story,” she said on Jimmy Kimmel Live! “I knew that [Bradley] had the vision for how it should go. And so I was like, ‘What do you think Bradley?’ And he laid it all out. And everything that you saw, the way that it was shot, the way that they push the piano out, you saw them, you know, put the piano together and walk up on stage, no intro — that was all [Bradley].”
