Millie Bobby Brown must have relied on Eleven’s supernatural abilities to hide her latest tattoo for so long. The actor added a tiny, blink-and-you-miss-it tattoo to her growing collection of ink months ago, and it’s been hidden in plain sight ever since.

Brown’s cowboy hat tattoo, delicately inked on her bicep, has made a few appearances in her Instagram photos, but it was first a recent photo dump that we could really see it in action.

It’s a quarter-sized cowboy hat drawn with fine lines, so it’s easy to miss at first glance. That may be why we didn’t notice it when she did posted a tropical snapshot during the holidays; if you squint, you can see it in all its yeehaw glory on her arm, and it pops up too in a Florence by Mills photo from April. However, she did not has the tattoo by the Enola Holmes premiere at the end of October, so it must have been a late-in-the-year addition.
