No one screws up quite as adorably as Jennifer Lawrence: While on a recent tattoo date with Liam Hemsworth’s family, J.Law decided to have her own “watered-down rebellion” and got a barely visible tattoo of the formula for water on her hand. (“Well, I’m always gonna need to be hydrated,” she explained.) The problem? It’s scientifically incorrect, which she realized after she noticed the “2” in H20 hangs higher than it’s supposed to. J.Law, just your average 20-something with a tattoo she probably regrets.
