^^ VS seem to be testing the waters with her. I'm guessing she's an option to fill a main role if the public responds well to her (being the face for VS Pink instead of Behati perhaps? Though i'm hoping main line too).
Good for her if that's the case. She's 27(?) now, so full-time high fashion isn't going to be realistic for much longer. She seems to have made a decision to be more commercial, if her latest campaigns are anything to go by, so who knows?
