Seth MacFarlane, Age 47 – Single

Even though he’s seen so much success over the years, something seems to not be working correctly in Seth MacFarlane’s case as he’s never gotten married. According to him, he’s not against marriage or anything, it just hasn’t happened yet. But surely, creating Family Guy and American Dad! must be keeping him on a tight schedule.

Interesting enough, one of Seth’s few public relationships was with Emilia Clarke. They dated between 2012 and 2013 but apparently didn’t last for long. They did, however, end things on good terms. He has, however, always been incredibly private about his romantic life.
