It’s being reported today that Eva Mendes is pregnant, and that her boyfriend Ryan Gosling is the father. This is splendid news. Really! Good for them. They’re a lovely celebrity couple. I’m sure they’re very good together, love each other very much, and will one day make spectacular parents.

But they are not a perfect celebrity couple. The perfect celebrity couple is such a rarity these days: Two celebrities perfectly matched, adorable together, with so much chemistry is just feels like they belong together and that the Earth almost insists upon it.

I feel like these perfect couples are a rarity today. Tom and Rita. Krasinski and Blunt. Emma Stone and Andrew Garfield. Penelope Cruz and Javier Bardem. But even those couples aren’t as perfect as these five couples who were always meant to be, and who — through sad circumstance and fate — simply refused to grow old together.

We still miss them dearly.

Ryan and Alanis . You let fame get to your head, R-Squared! You chose pretty blondes over substance. ISN’T THAT IRONIC?

Keri and Speedman — It should’ve been Noel on the show, but Ben and Felicity were meant to be together in real life for an eternity. They even had the same hair style!

Tim and Susan — How could you! You had children together. But more importantly, you should’ve stayed together for us! The public.

Ryan and McAdams — News of Mendes’ pregnancy must have sent a dull pang of sadness through McAdams, who no doubt let go many years ago, but understood that this is really it.

I’m pretty sure Blue Valentine was about them.

Johnny and Winona — A more perfect couple will never, ever exist. Johnny can move to France, shack up with a Parisian actress and ditch her for a 20-year-old lesbian blonde, but his heart will always belong to Winona. WINONA FOREVER.
