She could be shooting the cover tomorrow or Wednesday (or maybe next week)
It has to be this week (tomorrow), otherwise the stylists wouldn't have made requests for today. Wednesday, half of her team are busy.
I'm not sure what she's actually doing though (Not Madame, I checked) Thursday and Friday she's at The 02. Saturday she's off to a party / meeting
Edit: Which day are her dancers at Pineapple? I forgot.
