Meanwhile at Sundance, Bradley reportedly has a look-alike who is trying to get into parties by pretending to be him!

One fan took to his Instagram to share a photo with who he thought to be Bradley, but it looks like this may be the impostor!

Also pictured: Bradley taking a snowy stroll earlier that day in New York City.

FYI: Brad is wearing a Fjallraven coat. He is wearing a rag & bone blazer at the event.
