Over the years, celebrities have provided us with endless supplies of both incredible love stories and messy, dramatic splits.

And while we’ll always have a soft spot for celeb love, especially when they gush about each other in candid interviews, celebrities have also been quite messy in the past, too. In fact, some beloved Hollywood couples began their relationships as full-on affairs. Whether one or both of them were married when they first met, some of these love stories have been nothing short of unconventional.

In early 2025, Sutton Foster and Hugh Jackman were the latest couple to seemingly confirm cheating rumors. According to several reports, the two started dating when they starred together on Broadway’s Music Man back in 2021. The two were married at the time, but have since divorced their exes.
