This blog routinely reports on the break-ups and divorces of famous couples. This one is more heartbreaking than most. Poehler and Arnett have made a hilarious pair offscreen and on, teaming up in movies like “Blades of Glory” and on their respective TV shows, “Parks and Recreation” and “Arrested Development.” The actors — parents to sons Archie, 3, and Abel, 2 — also seem like pretty grounded people. Together, they were one of the rare Hollywood couples who seemed to have a solid chance at a lasting marriage. As silly as it might seem to feel sad about a split between two people that we don’t truly know, it’s really sad.

Or to put it in the Twitter terms of The Blogess:

Amy Poehler and Will Arnett Split.I want to punch this day in the face.

Poehler and Arnett will have to confront this situation in a high-profile way at the Emmy Awards on Sept. 23. It is devastating that as a result of their separation, we presumably won’t get to see them do a repeat of their Emmy red carpet routine from last year.

Here’s the video.

See how great they were together? Pretty great.

That’s it. Love is officially dead to me.
