Exactly what I was thinking...
At the end of the day, wasn't David the one who took, retouched, and submitted the photo with Sara's nipples to Lui?! If he was truly "defending" Sara on set, why would he then release and retouch a photo of Sara with her nipples out to the magazine? Especially if there was an agreement that went against nudity - which I'm sure he was aware of considering he is the freaking photographer! It's understandable that in some shots some nipples may pop out. But how did the photos go from his camera to the front cover? Wouldn't he have warned Sara if he was coerced into submitting that shot? She seemed genuinely surprised in her account of the situation that the nudity shot was used for the cover. I doubt the Lui people would have direct access to the footage, the photographer always handles everything. It's just shady. Maybe Sara doesn't want to burn her bridge with David since he's more involved in the fashion scene than say, Lui magazine?
