Irina Shayk's post-breakup swimsuit Instagram photo is a full on mood

Last week, it emerged that Irina Shayk and Bradley Cooper had decided to call it quits after four years together. It was reported that the pair's relationship had been on the rocks for a while, and that it was for the sake of their daughter that they tried to work things out.

Ultimately, though, Shayk, 33 and Cooper, 44 did decide to separate and are currently working out how to share custody of their two-year-old daughter Lea De Seine, according to People.

And while breaking up is never easy on anyone, regardless of how difficult the relationship may have been, it must be particularly hard if you happen to be one of the wealthiest, most successful and most-watched couples on earth.

Then again, people deal with breakups in very different ways - and some are decidedly better at bouncing back and at least appearing to have moved on.

Clearly, Irina Shayk is one of these people.

Yesterday, she posted a very striking post-breakup snap featuring none other than her own derrière.

Unsurprisingly, the snap was inundated with comments from the supermodel's admirers, who were seriously impressed by the gorgeous pic.

"Hands down the most beautiful woman on the planet," user ani.nyc gushed while irkara referred to Shayk as a "true Russian beauty".

But, of course, considering it's been less than a week since the breakup was officially confirmed, fans just wouldn't stop mentioning Cooper in the comments - and they weren't exactly singing his praises.

"Bradley is crying somewhere," afghan_queens speculated.

"Will always support you," wenjenm wrote. "Stay strong! Bradley is blind, gaga nothing near your status!

"Can’t believe what Bradley Cooper did," sabio28 added, without elaborating on what he was supposed to have 'done'.

Shayk is thought to have initiated the split, with many believing it may have had a little something to do with Cooper's undeniable chemistry with his A Star Is Born costar Lady Gaga.

Check out the pair's steamy performance at the 2019 Academy Awards back in February:

According to a source for People, "Bradley was emotionally absent during the long time filming A Star Is Born," while another source for ET revealed that they were on the verge of splitting during the film's release but were "advised against it".

"Recently, Irina decided enough is enough. She didn’t feel she was getting the level of commitment she wanted and the endless fighting made their life unbearable," the source said. "They are very different people, and once they realised it was the baby that was holding them together, it was time to call it quits."

"Some of their friends feel they never truly got a chance to know each other outside of being a family, and it was just all too much too fast."
