Couples are always being told by the media how to keep the fire of love burning, and Neil Patrick Harris has added his voice to the mix by telling the story of his own relationship. He told Glamour that when the Honeymoon phase ends, couples will have to find something else that turns both partners on, and for him and fiancé David Burtka, that something was having kids.

“Watching David become another level of person, mastering this other domain, made me look at him with a whole other set of appreciative eyes. That sort of made me re-fall in love with him. That’s another important thing to realize. Everyone falls out of love with everything. You fall out of love with your house. You fall out of love with your job. You just have to figure out ways to keep [the love] alive,” Harris advised.

So much to celebrate for greatest man I know! @ActuallyNPH I am so glad you were born. My life would not be the same! pic.twitter.com/3rGrzPTBT8

He and Burtka have adopted twins Harper Grace and Gideon Scott, who are both 3 ½ years old. He also shared some lessons he learned while parenting the twins, such as the time when Gideon asked to put on a dress because he wanted to play with sister Harper, who was enjoying her Disney Princess outfits. Harris said that he and Burtka let Gideon put on the dress, but that the boy realized he didn’t really like it after all. Harris told Glamour readers, “Let people be who they are.”

Harris is enjoying his latest projects, which include his leading role in Hedwig And The Angry Inch, which requires him to perform in high heels. “Initially, walking around in heels is a very challenging thing for a guy to do. But once you’ve done it six or seven times, it’s weirdly empowering,” he said. The How I Met Your Mother star is also set to come out in the upcoming David Fincher movie Gone Girl.
