I’m BFF-status with Cameron Diaz because…
She’s my sister, but we bro out and have crazy adventures. Most people don’t know this, but she’s very edgy.

My go-to accessory is…
A heart-shaped locket from my husband, Will Kopelman

My guilty pleasure is…
Carbs, carbs, carbs!

The fashion item I can’t live without…
Button-down flannel shirts.  They’re easy, they’re grungy— but if worn right they can be more sexy than frumpy.
