Neil Patrick Harris
"This is a sore subject because we are two gentlemen with children. And so we didn't know what to call ourselves. Daddy One and Daddy Two sound kind of strange… So David's 'Daddy' and I'm 'Poppa,' just to differentiate."
Neil Patrick Harris, 39, and David Burtka are dads to twins Gideon Scott and Harper Grace, born October 12, 2010, via surrogate.
