10 Celebrity Couples Who Fell in Love After Playing Onscreen Siblings

As foul-mouthed detective Debra Morgan and sociopathic serial killer Dexter Morgan, onscreen siblings Jennifer Carpenter and Michael C. Hall had tons of scenes together on Dexter. Working in close quarters no doubt led to their decision to start dating in 2007 and their elopement on New Year's Eve in 2008. After they appeared at the Golden Globes for the first time as a married couple in January 2009, Michael announced that he had Hodgkin's lymphoma, and Jennifer stood by him through it all until their divorce in December 2011. Though their romantic relationship ended, their working relationship continued for two more years until Dexter's series finale in 2013. Awkward.
