Dax Shepard and Kristen Bell
These two have been together since 2007. They got married in a low-key ceremony in 2013 and have two children. Both admitted that there were 0 sparks when they first met, but after a while, they realized they were soulmates. They're also no stranger to couples therapy and advocate for continuing to take the time to get to know each other, no matter how long it's been.
