Irina Shayk and Bradley Cooper have kept a very private relationship since they began dating in 2015, but sources say the two may be calling it quits soon.

An insider told New York Post's Page Six, "Things are not good. Neither one is happy," adding that the relationship is "hanging by a thread."

This is not the first time there was speculation about relationship drama, as both are said have different interests when it comes to how they enjoy spending their free time. Another source told the site in October that while Shayk likes to go out on the town, Cooper is more into staying in. "They are miserable together. They have been for months. He doesn’t drink and is into spirituality. She wants to go out."

The latest insider said about Cooper and Shayk, “Because of their daughter, they keep trying." The pair welcomed Lea De Seine in 2017.

It likely does not help matters that there have been plenty of rumors circulating about Cooper and his relationship with "A Star is Born" co-star Lady Gaga, as the two had undeniable chemistry onscreen and at various red carpet appearances following its release last fall. Gaga addressed the rumors in February, telling late-night host Jimmy Kimmel, "...People saw love, and guess what? That’s what we wanted you to see."
