i believe that Izabel is extremely lovely. she has always come across as nothing but perfectly charming and delightful in interviews. so any rumour of a "diva" attitude i will have to simply dis-believe.
i think the article about the "crying" over the wings has simply mistaken Izabel for Lily Aldridge. it's Lily's first set of wings this year and she mentioned in one of the casting videos how she cried when she got them, how it was such an honour, etc. SO -- since Izabel has already been a contracted VS Angel in the past, and has already worn wings .. and since Lily has said this -- I think it was simply an error by the author of the original article.
either way -- CANNOT WAIT to see Izabel at the VSFS this year! last year, the blue/pink outfit was one of my favourites .. and her pose at the end of the runway, butt out, over the shoulder, hair-held-up-with-one-hand-above-her-head ... *wow*. indescribably hot. best pose of the night, bar none.
