->''"Aww, I bet those two are gonna get married. In real life. Which they did."''

A pair of performers fall in love while working together, possibly even getting married and/or having kids over time. This happens quite a bit in Hollywood and is prime tabloid fodder. Such relationships seem to have a high breakup rate, but there are some long-lasting marriages that started this way.

What is actually being filmed is largely irrelevant. They're often a couple onscreen as well--when you spend all day pretending to be in love with someone, you may end up BecomingTheMask. However, it doesn't always happen that way. The point of the trope is that behind the scenes the two fall for each other.

TheMuse is a SubTrope, which is about a male movie director falling in love with his lead actress. CastIncest is another subtrope, namely the first type where the couple met while playing relatives, which adds a level of {{Squick}} before further thought reveals that it's no different from any other role.

In live theatre circles, the phenomenon is known as a "showmance" and tends to [[SickeninglySweethearts annoy their costars to no end]].

Compare ActorShipping, where the fans ''want'' this to happen. Contrast HostilityOnTheSet, where the actors loathe each other.
