#14: Ian Somerhalder and Nina Dobrev
This situation highlights why mixing romance with work can be tricky. While filming The Vampire Diaries, Nina Dobrev and Ian Somerhalder were romantically involved, but their relationship ended midway through the series. Following the breakup, both actors were reluctant to participate in kissing scenes.
Unsurprisingly, on-screen kissing scenes became scarce after their split. Their breakup also seemed to impact their chemistry on-screen, with some fans noting a decline in their connection. It’s a reminder that personal dynamics can significantly affect professional relationships, especially in a setting as intimate as a film set.
