A source told ET last week that Shayk and Cooper's split was "no surprise" and that the model initially "had high hopes" for her life with the 44-year-old actor but his work schedule took a toll on their relationship.
The singer however, hit back at these claims during a performance in Las Vegas over the weekend.
Their sizzling chemistry and intense gazes sparked speculation that the Star Is Born co-stars were in the midst of a dramatic love affair.
"There's no way Gaga and Bradley will get together", the insider told The Sun.
The pair played romantic partners in A Star Is Born which did incredibly well. "Because I thought they were shallow".More news: Google Assistant has finally arrived in Waze
Speculation of a romance formed nearly immediately after the performance. "And guess what? That's what we wanted you to see".
But people are drawing connections between the choice of song and her final words.
Indeed, the couple - who are parents to two-year-old daughter Lea De Seine - put on a fearless face when they hit the awards circuit together at the start of the year.
A source told E!
'They want to stay together for their daughter, but neither of them are very happy'. Sources also add that for the past few months, the two were reportedly living separate lives and were actually spending the majority of their time apart.More news: Huawei Devices Could Be Blocked From Using WhatsApp And Instagram
'They are trying out different arrangements and trying to find their way'.
The duet earned the pair a standing ovation with their stunning rendition of the song, but fans began speculating as to whether there was anything romantic between Gaga and Bradley - despite the fact that Irina Shayk, the mother of Bradley's two-year-old daughter Lea, was in the front row.
Sources say, 'Irina decided it would be best if she moved into her own place'.
