What is wrong with her neck?
The twins LOVE to pose with their necks tilted like that. You see in most of the pictures.
I suppose they think it makes them look sexy.
It gets that way when you constantly turn toward the camera during your “scenes”. Typically, it also involves pulling her hair away from her face so as not to hide any portion of the other actors in the “scene”.
I think that’s called “the gangsta lean”.
