Babe of the day: Mary Elizabeth Winstead
There are several well-maintained on-line galleries of Winstead, like this and this. This pic of Winstead with her husband Riley Stearns appears to be from or close to the time they first met (2002-03, when she was 18 - he looks to be the same age). A youtube video of their wedding photos.
While I haven't read anywhere that she's mixed-race, Winstead has a strikingly Meg Tilly-esque HAPA look. I wouldn't be surprised if I learned she has Chinese blood.
Speaking of HAPAs, I suspect Winstead will age as well as Phoebe Cates.
