It's OK, it's just the dress rehearsal - and, by the looks of things, the Victoria's Secret official Instagram were more than happy to post shots, therefore breaching the strict "show confidentiality" rules...
This one was captioned "Shhh...so many #VSFashionShow secrets about to be spilled. Follow us tomorrow!!"
Followed by "Backstage babes: @kendalljenner & @behatiprinsloo at today's #VSFashionShow rehearsals. Can't wait for you to see their looks!!!"
And people didn't have to wait too long for Behati's "look"...
Meanwhile newbie angels Kendall Jenner and Gigi Hadid seemed to be getting into the swing of things...
The genetically blessed will charge around in their jewel encrusted bras in New York on December 8th to the strains of Selena Gomez and The Weeknd (Rihanna dropped out...) Until then, here's Alessandra Ambrosio bidding you good night.
