Big Brother urges both houseguests and viewers to "expect the unexpected" each season -- and that's typically ending up including at least one Big Brother showmance couple on every season of the long-running CBS reality competition.

Big Brother launched on CBS in 2000 and numerous showmance couples have developed during the 23 years the reality show has been airing on the network.

While some showmances on Big Brother seemingly came to fruition due to boredom or a desire for attention and affection, many of Big Brother couples actually went on to solidify genuine, long-lasting relationships outside of the house.

In fact, several Big Brother couples are engaged or married today -- and some of them even have children, including Season 20 couple Bayleigh Dayton and Chris "Swaggy C" Williams, Season 19 couple Jessica Graf and Cody Nickson, Season 12 couple Rachel Reilly and Brendon Villegas, and Season 11 couple Jeff Schroeder and Jordan Lloyd!

Viewers have seen been many Big Brother showmances to come and go on Big Brother, so let's take a trip down memory lane and look at some of the most memorable couples. Which Big Brother showmances worked out and which ones fell apart in the real world?

Did Paulie Calafiore and Zakiyah Everette ever end up being more than just a hookup? And what ever happened to other pairs like  Jessica Hughbanks and Eric Stein?
