You know when you're leaving the gym all sweaty and gross with your hair up in a crazy looking top-knot bun? Did you know you can leave there and go directly to an LA party? Well, you can. Kaley Cuoco did it. (I know. Who? She's the girl on The Big Bang Theory. As if that clears anything up.) She wore this, um, low-effort hairstyle to a party celebrating her show.
