While some are fretting over Anna Wintour’s white tie dress code, model of the moment Kate Upton isn’t sweating it.

“I’m naturally glam!” a coquettish Upton told Threads at the movie premiere of “The Other Woman,” in which she stars with Cameron Diaz and Leslie Mann.

When asked who she’s accompanying to the Gala this year, the bombshell kept mum: “It’s a surprise. I’m horrible at surprises; we’ll see if I can keep this one.”

Sadly, we can’t — sources say the beauty will go as the guest of Italian designers Domenico Dolce and Stefano Gabbana.
