The 33-year-old star also addressed rumours that she and Bradley, 44, who shares his 2-year-old daughter Lea De Seine with his ex-girlfriend Irina Shayk were dating.
The gossip hit fever pitch after the co-stars performed the song 'Shallow' from A Star Is Born at the Oscars in February, and their chemistry was palpable.
“We made a love story,” she told the magazine.
“For me, as a performer and as an actress, of course we wanted people to believe that we were in love. And we wanted people to feel that love at the Oscars.
"We wanted it to go right through the lens of that camera and to every television that it was being watched on. And we worked hard on it, we worked for days. We mapped the whole thing out — it was orchestrated as a performance.
"In truth, when we talked about it, we went, ‘Well, I guess we did a good job!’” she confessed.
Bradley and Irina called it quits in July, with a source telling Us Weekly that his relationship with his A Star Is Born co-star "had a major impact" on their relationship's failure.
“Even though there was nothing romantic between Bradley and Gaga, the noise was difficult for Irina to deal with,” the insider told the publication.
Bradley and Irina, who announced their split in July after four years of dating, share custody of their daughter, who they welcomed in March 2017.
Despite calling quits on their romance, the proud parents are maintaining a healthy relationship for the sake of their daughter.
