9 Actors Who Fooled Around With Their Co-Stars

Sometimes, when shooting a movie, two actors can get really close, especially when there are steamy scenes in the script. Naturally, this isn’t a problem unless one or both of them are currently in a relationship, but if they do have a special someone waiting for them at home, that’s a whole different story.

Let’s take a peek behind the scenes and see which actors and actresses got a little too frisky with their co-stars when the camera wasn’t rolling.

1. Tom Cruise & Nicole Kidman

Tom Cruise and Nicole Kidman were an iconic ’90s couple, but their start was shady, to say the least. When they met on the set of Days of Thunder, Cruise was still married to Mimi Rogers. Then, out of the blue, Cruise divorced Mimi in early 1990 and, a few months later, married his newly found passion—Nicole Kidman. They starred together in Far and Away and Eyes Wide Shut before signing divorce papers in 2001.

2. Claire Danes & Billy Crudup

2003 brought one of the messiest celeb cheating scandals. Billy Crudup was with a pregnant Mary-Louise Parker, while Claire Danes dated musician Ben Lee. After Danes and Crudup worked on Stage Beauty, rumors flew, and sure enough, both ditched their partners. Crudup and Parker split by year’s end, and Danes later admitted on Howard Stern’s show that she was young and didn’t realize the fallout. Their romance fizzled by 2007, but the drama lives on.

3. Dominic West & Lily James

Dominic West’s scandal with Lily James might not have ended in a divorce, but it sure rocked headlines. In 2020, cameras caught West, who has been married to Catherine FitzGerald since 2010, getting cozy with Lily James in Rome. Photos of them smooching out in the open went viral, but the couple made a public show of staying together, saying their marriage was “strong.” As of 2024, Dominic and Catherine are still married, proving not all cheating rumors can ruin marriages.
