The naked lady added what exactly? I get that they want to show that he's mature and has left Disney, but they couldn't communicate that without a nude woman? It's just another chance for men to see a nude woman in the name of Art. It could've never have been one of the girls with a nude man, because they would've screamed sexism and spoke about the objectification of men but, oh, since it's a woman that's displaying her body then that's okay? Oh, please.
Besides, love Zac as I do, these photo shoots really need to stop. He's an Actor - not a male model - and if he wants to be taken seriously, they need to quit putting him in uber-tight t-shirts and throwing him in front of a camera -- just let his talents and intelligence speak for itself.
