Fashion: The new androgyny

After the billboard success of transgender model Lea T, comes the next gender-bending face of fashion, the Serbian-born Australian model Andrej Pejic. With his flowing blond locks and pixie pout, he's the androgynous face of Marc Jacobs' newly launched spring/summer ad campaign, and stars alongside female lookey-likey Karolina Kurkova for Jean Paul Gaultier. We don't know whether to fancy him or envy him.

Face to watch: Jessica Chastain

She starred recently in Murder on the Orient Express, but no grey cells are required to deduce that this 29-year-old is primed for bigger things, with roles in Mossad thriller The Debt and Terrence Malick's long-awaited The Tree of Life.
