Indeed, the 5' 3" actress, who once joked, "My idea of aerobics is going for a slice," is designing a line of streetwear for Reebok, and tells InStyle in its new issue that the clothes are "fitted to my body. So I know they'll fit a regular person."
The 21-year-old Black Dahlia star says her favorite indulgence is a slice of veggie pizza and a Diet Coke or a wedge of homemade key lime pie (she loves baking). A typical dinner is Chinese takeout: "A little white rice, a little chicken, some egg drop soup …"
And though she's glam on the red carpet, in her everyday life, she says, "I'm pretty casual. I wear sneakers and flats. I can walk in heels, but do I wear them every day? Certainly not. Only if I'm going to a premiere or a party, because I like to look like a lady."
One thing she'd like to wear – someday – is a wedding gown. "Of course I want to get married, but I'm way too young," she says. "I'm not ready to sacrifice a lot of things in my lifestyle just to have an engagement ring."
And despite her successful acting career, she wouldn't mind giving it all up – for a day. "Whose life would I like to step into for the day? The President's," she says. "I could probably get some things done in the Oval Office."
