Cobie Smulders and Taran Killam – 8 years
Cobie Smulders rose to fame through her role as Robin Scherbatsky in the popular sitcom How I Met Your Mother (2005-2014). She and Taran Killian bonded over billiards and jazz in the city of New York – which is not very different than the way Ted and Robin meet on the show. The two quickly fell in love, and the rest is history!

Now the couple has been together for almost a decade. Funnily enough, Taran actually appeared as one of Robin Scherbatsky’s short-lived love interests on How I Met Your Mother. Now, Cobie Smulders and Taran Killian have had two daughters together and a bright future ahead.
