As part of the festivities, the leaders attended a big military parade on the famed Champs-Élysées on Friday.
During the ceremony, a French army marching band played an amazing cover of a bunch of Daft Punk songs. (The electronic duo are French, in case you forgot.)
But Trump and Macron had two, err, rather different reactions.
Macron's all, "I'm digging this because I'm a hip, young president who grew up dancing to these sick beats in la discothèque."
While Trump is, umm, not thinking those things.
Here's Macron smiling as he reflects on how the French robots made a seamless transition from house, to electronica, to dance music.
As some pointed out on Twitter, perhaps the 71-year-old Trump simply hadn't heard "Get Lucky" before.
And many, many people noted Trump's hair, at least, was bopping along to the beat.
To be fair, Trump did give a hearty round of applause, and even a whistle, when the song was over.
Also, let's be honest, "Get Lucky" was way too overplayed.
