In response to reports that her shade -- where she calls out an unnamed person for spending the entire fashion event on his cell phone -- during the trailer for The First Monday in May was directed at Allison Williams' husband Ricky Van Veen, Vogue offered ET a tight-lipped but polite response.
A spokeswoman for the publication wouldn’t confirm whose name ticked off Wintour, but said, "Ricky was a perfect guest, and we look forward to welcoming him back this year."
Backing up a bit, The First Monday in May documentary details the all the behind-the-scenes legwork that must happen to pull the Met Gala together. During the trailer, Wintour comments on a guest who decided to attend at the last minute: "OK, can he not be on his cell phone the entire time then?"
ET caught up with the film's director, Andrew Rossi, at the NYC premiere during the Tribeca Film Festival Wednesday night, who commented on all the speculation, including gossip that Justin Bieber may have been the target of Wintour's ire.
"Anna does talk about making sure no one is using their cell phones and there is one moment where she’s talking about a specific guest," Rossi explained, "But unfortunately... we don’t know exactly who it is."
