I mean, Naomi Campbell used a surrogate for her two children, so she's clearly OK with the concept of renting another woman's body...
I don't think these photos prove anything. A frozen moment in time, it could have been anything. I'm not even sure who/what she's looking at.
But given her history of blood diamonds, violence, etc, would I be hugely surprised if she knew and/or turned a blind eye? No.
