Aw! Newlywed Neil Patrick Harris guested on David Letterman’s show last night and shared some super sweet deets about his marriage to David Burtka. Watch the video below to hear Harris tell Letterman why they chose Italy (it’s not because George Clooney was getting married there!) and the story behind their first dance song (Kelly Clarkson’s “A Moment Like This”). We’ve got even more adorable details from the grooms’ wedding here.
