the preview shot from around 8 weeks ago is emrata. you can tell by the barcode tattoo just above the back of her left ankle http://www.pinterest.com/pin/149955862567402564/
and at nine seconds, still worth watching carmella lookbook behind the scenes http://web.stagram.com/p/516079977518586659_212013061 a different view of the longer video here:https://vimeo.com/75514028
i'm not savvy enough to extract the pictures but there's a lot of fantastic material here: http://issuu.com/threadsence/docs/threadsence_the-finest-hour?e=2245567/
and apparently that picture of her and a bidet led to a fashion campaign with yamamay: http://www.fashionpathology.it/2014/06/emily-ratajkowski-testimonial-della-prossima-campagna-yamamay/4229 (at least that's the way this blog characterized it)
don't think it's been discussed in this thread, but i'm about 95% sure emrata will be in SISI 2015 see evidence here: http://www.bellazon.com/main/topic/51935-2015-si-swimsuit/?p=3411643
btw, it's definitely the return of emrata. you can tell by the small tattoo on the back of her left ankle seen here: http://instagram.com/p/nT3oOZEnh3/# and matching the one in this NSFW shot:
