Through a decade of blissful partnership and fraternal twins
, there's got to be some kind of formula that makes things just click for Neil Patrick Harris
and David Burtka.
The lovey-dovey duo appeared on an upcoming episode of RuPaul's Drag Race
, where they were put on the spot about the success of their love.
"What's the secret to your relationship?" Ru asked.
With only a quick moment of hesitation, Burtka, 38, responded, "Oh, wow, umm, never go to bed angry."
But it was Harris, 40, who came out with the kicker, telling the host, "Yeah, I haven't slept for six months."
All kidding aside, the pair have openly expressed their heartfelt love for one another.
"Without him, I can't breathe," Burkta has said
. "The biggest thing is that he makes me laugh, but he's also smart. He can do everything. I'm not kidding; I think he's half robot. He makes me a little more grounded, and I bring out the wild side in him."
