Neil Patrick Harris stopped by Late Show With David Letterman on Monday, sweetly sharing stories and pictures from his recent nuptials. Neil and David Burtka tied the knot in Italy earlier this month, and the actor told Letterman about some of the most special moments from their wedding. He said that Elton John introduced their first dance, which was done to Kelly Clarkson's "A Moment Like This" because the two have loved Kelly ever since her American Idol days. Neil also dished on an extraspecial moment from their first dance, sharing a picture and joking, "Take that, Clooney!" Watch the cute interview above, and then check out more pictures from Neil and David's wedding!
