Months later, Shayk attended the 2019 Met Gala alone. The couple had walked the red carpet together just one year earlier.
However, the couple has kept their relationship private from the very beginning, rarely commenting about their romance to the media. The pair first sparked relationship rumours in April 2015 when they were spotted attending a Broadway show together. After that time, cameras continued to spot Cooper and Shayk together at places around the world, which seemingly confirmed their romance.
Then, about two years after sparking romance rumours, the couple welcomed their first child together.
This week a source allegedly told Page Six, "Because of their daughter, they keep trying. Things are not good. Neither one is happy."
While another source reportedly told E! News, "Things get a little bit better but then they find themselves back in the same place of questioning whether being a couple is what's best. They want to stay together for their daughter, but neither of them are very happy."
"They've spent time apart to test the waters and see if they are better off," the source continues. "They have a lot invested and it's very difficult to completely walk away from. They are trying out different arrangements and trying to find their way. They love their little girl dearly and that's not going to change no matter what."
Another report from The Sun claimed the Russian model has moved out of their shared home. "Things are cooling off between Bradley and Irina in a big way," an alleged source told the publication. “They haven’t been good for a few months and Irina decided it would be best if she moved into her own place."
“It’s not looking like there’s much long left for the two of them together.”
While reports have confirmed the split, the couple is yet to formally comment.
