Katie Holmes

I think she's trying out more than just bangs. I've seen here several times promoting her current film and it look like she's wearing a full wig to me. The hair has no real part and all comes from the center of the to top of her  head. Also, the hair's texture and volume doesn't look like her normal real hair at all. My guess is she just didn't want to have to get her hair fixed six times a day for this promo tour and is just going the easy way.

They're fake but they're still pretty cute
