As tempting as it is to believe that celebs miraculously wake up looking totally camera-ready with little to no effort at all, there are a few brave souls out there that are daring to show us, once and for all, that that’s simply not the case.

As plus-size model Iskra Lawrence works to debunk perfect body illusions, Jennifer Garner, 45, (who just joined the wide world of Instagram earlier this month), is giving us a glimpse of what she *really * looks like upon first awakening.

While she’s still predictably gorgeous, she’s also plenty relatable, fiending for her morning cup of joe before she’s even left the bed. The The Tribes of Palos Verdes actress had good reason to be tired: As she explained in her post, she spent the night before having a “Yes Day!” with her kids.

For those who are unfamiliar, “Yes Day!” is based on the children’s book ($10) of the same name by author Amy Krouse Rosenthal, and is explained as “one day of the year kids when kids can always receive positive answers.”

For the mother of three, it was quite the affair, including a camping stint in the backyard. “You’ll never need coffee more than the day after “Yes Day!” she wrote. “#wesleptinatent #inthebackyard.” Awww!

Luckily, yesterday just so happened to *als* be #NationalCoffeeDay, we’re fairly confident she got her fix.
