During her never-ending campaign to be as cool as her husband, Michelle Obama has tried to break the world record for kids doing jumping jacks, danced like a hero and beaten talk show host Jimmy Fallon in a sack race.
Today, more information has emerged on Michelle's latest bit of awesomeness - namely, photobombing Julia Louis-Dreyfus at an official dinner.
Revealing just what happened on Late Night With David Letterman, the one-time Seinfeld star brought along a snap she had taken where the First Lady can be seen in the background, waving away.
As for why Ms. Louis-Dreyfus was on the talk show in the first place, well, that's because she's got a new show out on HBO called Veep, which we heartily recommend here at Huffington Post UK Comedy.
