No he didn't
He's been posting random pictures of celebrities at the met ball because the event is coming soon and he's one of the people who organizes the event.

Madonna loves going there, so I wouldn't be surprised if she does attent, but his posts HAVE nothing to do wish her being on Vogue

thanks for clearing that up, i must be too dumb to read the signs.

It's because she'll be on the cover of L'Uomo Vogue in a few weeks. She posted several pics of the photo shoot on Instagram (the one with the armpit hairs for example).

Isn't the MET gala organized by Vogue?

lol she is going to be on the male version of the italian Vogue soon
