While most of the celebs on this list have moved on with their lives, we're still not over these perfect ex-relationships! E! News rounded up four of the cutest couples of yesteryear in the video above, complete with adorable footage of these pairs back in the day.
Justin Timberlake and Britney Spears: This '90s teen idol power couple were one of the most adorable things to ever grace a red carpet — Canadian tuxedos and all.
Jennifer Lopez and Puff Daddy: With all of J.Lo's high-profile relationships (Bennifer the First!), it's easy to forget that she once dated Sean "Puffy" Combs — when he was still Puff Daddy, the first time around.
Nick Lachey and Jessica Simpson: Although these two brought out the worst in each other in many ways — we're sure the reality show didn't help — part of us misses the Newlyweds days. Life was so simple back then.
Rachel McAdams and Ryan Gosling: These two broke it off right when we started believing they were an actual, real-life couple and not just a The Notebook-induced hallucination. We're still ugly-crying over it. Baby Goose does look pretty cute with Eva Mendes, though… Isn't there enough Ryan to go around?
