24. Jesse Spencer and Jennifer Morrison
Jennifer Morrison and Jesse Spencer met in 2004 while filming the pilot episode of House. Their attraction was almost immediate because the two began dating four months later. In what seemed like a whirlwind romance, Spencer and Morrison were engaged a couple of years later. Things were, in fact, too good to be true.
The two didn’t end up getting married and publicly broke off their engagement in 2007. It didn’t work out for their House characters, either. Their characters, Allison and Robert, got a divorce in season six, and Morrison was essentially written off the show. Both actors have moved on to other successful relationships, and we wish them all the best.
