Yes, I've seen that he has worked with many big artists. I still think that a sylist doesn't have the right expertise to be a jury member. Maybe, if the the jury was made of 20 people, a stylist could be a nice addition to judge the staging, but with only 5 members I think it's a waste.
Ok, but he's not only a STYLIST. :? He has been ALSO a stylist for Emma. He's an art director, a music video director, a film maker and many other things. He's better as a juror than a "journalist", they only write about showbiz, he lives and works for the showbiz. But it's my opinion.
