A romance between to television, film and theatre actors or realty stars who play the role of the others romantic interests in a television series, play or film (see; reality television). This typically occurs when two actors share one or more scripted "love" scenes or on-screen kisses.
Showmances do, however, develop between two
co-stars playing roles in which they are in no way romantically linked, however due to
long hours on set and often odd or isolated locales, a couple
may develop some sort of relationship to bide their
time or otherwise entertain themselves.
An actor or actress
may mistake scripted passion or
chemistry on screen, for a real life romance off-set. Showmances typically end after the filming has ended.
Brangelina showmance is one of the longest
running in
history.
(see "House: MD" co-stars; Jennifer Morrison and Jesse Spencer; now engaged, they started their romance around the
time it was written into the show)
