Just watched the cover video on elleuk.com (here)Apparently they used a bleach blond hairpiece/wig for the shoot instead of her own hair... Bit ridiculous considering she has fabulous hair. You can also tell how much photoshop has been used - she looks so natural and vibrant in the video, but in post-production (the newsstand cover) she definitely looks plastic.
Not a good move on both accounts, I must say...
I may not be perfect, but neither was Tom Ford SS12. And that's good enough for me.
