My boyfriend has worked with Mario Testino (a few years ago now), and he confirmed to me that whilst he didn't do anything to him on set, he was a bit lewd and sleazy. And there were stories (that he heard, so can't confirm the veracity of this statement) of him trying to take straight guys and make them gay
The shoot was for a big brand, and mixed cast with loads of people on set, but in my boyfriend's words 'I feel like he would definitely have take advantage of the models if they were in a more closed environment'.
Mario Testino apparently asked personal question to one of the girls, she revealed she was a virgin, and he subsequently walked around the set repeating that to a few people.
He (my bf) also said that he seems to 'enjoy his position of power,' and definitely takes advantage of that.
My boyfriend said there is quite a division between the male and female modelling industry, so unfortunately I haven't been able to get that much insider goss that pertains to these forums, and I guess it's nothing we sort of didn't know before.
He doesn't usually talk about his job or the modelling industry but was quite talkative this morning so I took advantage of it haha
