John Stamos and Lori Loughlin of Full House
Character names: Jesse & Becky Katsopolis
Years dated in real life: 4 months
In the late '80s, Uncle Jesse and Aunt Becky were briefly romantically linked in real life. These two stars, who seemingly haven't aged a day since the show's cancellation, dated in late 1988. Though they were happily married and had two twin sons on this sappy sitcom, their real life relationship lasted only four months. It was a quick, whirlwind Hollywood romance. Have mercy!
