Anna Wintour, what were you thinking?

Sandra Bullock's Vogue cover has been revealed and while the actress looks gorgeous as usual, we're a bit confused about her hair.

Is it a fancy mullet? A chic bouffant? A beehive? We don't know!

While we love the green sequined Marc Jacobs dress (just look at that sexy back!) we can't stop staring at Sandy's mystery 'do.

The October issue of Vogue (which is Sandra's fifth cover) is on newsstands just in time for the release of the 49-year-old's new movie "Gravity," which garnered favourable reviews at the Toronto Film Festival.

Sandra looked Oscar-ready at the TIFF 2013 premiere of "Gravity" wearing a colour-blocked dress and changed into a hot pink body-con frock at the film's press conference.

Let's just hope that when it comes time to dress for award season, Sandra loses the Vogue hair!

We still love ya, Sandy:
