Bradley Cooper and his ex, Irina Shayk spent some quality time together and fans couldn't help but think about a possible reunion.

The 36-year-old Russian supermodel, who shares a five-year-old daughter named Lea De Seine with the actor, shared a series of photos on Instagram on Sunday.

In the first photo, Shayk can be seen relaxing on the beach in a bikini, next to a huge pig. In the next photo, the model can be seen swimming in the water alongside little pigs.

In one of the photos in the carousel post, 47-year-old Cooper shares the frame with the supermodel resting her head on his shoulder. Both are all smiles as they posed for the photo.

The remaining photos include some of Shayk's solo snaps with more pigs and fishes. She also shared a video featuring pigs walking on the sand. The supermodel just added a heart emoji in the caption of the post.

Instagram users shared their reactions in the comments section.

One of the users wrote in the Russian language, which translates to, "I wanted to joke on the first shot that Irishka is hanging out with her ex, but it turned out to be no joke."

Another user questioned, "Back together??" Many more users speculated that the former couple is back together.

Cooper and Shayk first began dating in September 2015 and made their relationship official in March 2016. They welcomed a baby girl in March 2017. However, after five years of dating, the two decided to part ways.

While Cooper has not been romantically linked since their breakup, Shayk dated Kanye West from March to August 2021.

On the work front, the actor was last featured in the Marvel movie, "Thor: Love and Thunder," where he lends his voice to Rocket's character.

Considering his upcoming work, Cooper will lend voice to Rocket's character again in "The Guardians of the Galaxy Holiday Special," which is slated to release in December.

Aside from voice acting, the actor will also be directing and starring in the movie, "Maestro" where he will portray Leonard Bernstein's character. This is his second directorial venture since the highly successful "A Star Is Born," starring Lady Gaga.

Shayk, on the other hand, was last seen in the music video, "Waareftak," which was dropped in May this year.
