Neil Patrick Harris and David Burtka – 16 Years
David Burtka and Neil Patrick Harris have been married for over a decade, having met in 2004. David Burtka was in a long-distance relationship that was on the verge of failing at the time.
Even though they began as friends, things heated up quickly. In 2007, Burtka proposed to Harris on the spot where they first met, and they wed in Italy in September 2014.
