Shayk, who shares two-year-old daughter Lea De Seine with Cooper, has been in the public eye following the split - which happened days after the New York Post exclusively revealed last week that the couple's relationship was "hanging by a thread".
As for Irina, there were several speculations hinting that Gaga's closeness with Bradley was causing a problem in her relationship with the A Star Is Born actor. They are both wonderful parents, ' the source indicated. Could Irina and Bradley have separated during this time? Then there's the fact that they never got married after they had a kid.
There has been no source or evidence to suggest that Gaga had anything to do with the couple's split.
"Because of their daughter, they keep trying", a source told us at the time.
"Recently, Irina decided enough is enough", the source continued. It's possible the real reason they didn't say much about their relationship was that they had already split up.
A Star Is Born was important to Cooper because this was his directorial debut. This was also the first time he sang a featured song on camera. One of them being Lady Gaga's ex-fiance Christian Carino.
Cooper was dressed in a red track jacket, jeans and Nike sneakers - a far more covered- up look than what Shayk, 33, was wearing in her most recent Instagram snap.
"After awards season ended, Cooper slowed down to focus on his family", the insider said, sharing that the star spent "every day with his family". Before that, he had reportedly been spending a lot of time alone so he could make music for the movie.
