There’s something so fascinating about celebrity costars who have dated. Picture it: You’re watching your favorite characters share an intense moment in a movie or TV show. Maybe they’re fighting in the rain (ahem, One Tree Hill) or trying to escape White Walkers (you know nothing, Jon Snow). Suddenly, you feel…something. Is it excitement? No. Anticipation? That’s not it. Chemistry? Ding ding ding.
With the right smoldering look or gesture, chemistry between two leads can make us overlook some of the most unrealistic storylines (sorry, Riverdale). It’s even more enticing to watch when you know those onscreen feelings match offscreen feelings, too. Celebrity costars who dated in real life give us moments that keep fans coming back for more–even if the IRL relationship is long over.
