The American publication Life & Style revealed that Gaga and Cooperstar were 100% together, however for obvious reasons never made the status of their relationship public.
"There’s no doubt about it - Lady Gaga fell head over heels for Bradley during filming and promotion ofA Star is Born," a source told the magazine. "She thought he was 'the one' and assumed he felt the same way – until recently."
Those close to Lady Gaga fear that she is being "strung along" by Bradley regardless of him backing off from the fling.
"She’s telling friends he broke her heart," reportsLife & Style.

"Gaga feels like Bradley led her on because he was giving off all the signs that they’d become an item once he was single," said the magazine's source, referring to Bradley's split from his girlfriend of five years, Irina Shayk. "He suddenly realised he was jumping into a full-blown commitment to someone else and got scared."
Bradley and ex-fiance, Victoria's Secret model Irina Shayk shocked the world when they broke up in June.
An insider told PEOPLE magazine that they were "amicably working out how to share custody of their daughter Lea De Seine."
"Because of their daughter, they keep trying," a source close to the couple of five years also told Page Six, at the time, adding: "Things are not good. Neither one is happy. The relationship is hanging by a thread."

When Bradley was going through the breakup, he turned to Gaga for relationship advice.
"He goes to Gaga for advice over everything, which is pretty insensitive at a time like this but Bradley can’t help himself,” an insider told Radar Online.
The source added: “He’s just totally spellbound by her and thinks she’s the wisest, coolest and most worldly person on the planet. Gaga’s in a tough spot because she doesn’t want to rub Irina’s nose in it. But still, she does adore Bradley so she’s happy to take his calls."
Sure, there's been no official confirmation about Gaga's involvement in Bradley's life... but it doesn't take much to see that she played a role in the split between him and Irina.
While both expressed their chemistry was solely for the cameras, nobody believed them! Especially after their steamy Oscars performance.
"Yes, people saw love and guess what? That’s what we wanted you to see...When you’re singing love songs, that’s what you want people to feel," Gaga said.
