Dakota Johnson flashed X17 photographers the slightest smile when we caught her out and about in Los Angeles today, but she wasn't in the mood to chat -- and she totally snubbed fans in a TMZ tour bus!

The 25-year-old actress may be on the current cover of Vogue, but before it was announced that she was starring in Fifty Shades of Grey, we honestly had no idea who she was. And that movie isn't even out yet!

We're very curious to see Dakota tackle the role of Anastasia Steele (not to mention Jamie Dornan star as the delicious Christian Grey), but don't you think Dakota should be a little bit friendlier if she's gearing up to promote one of the most hotly-anticipated movies of 2015?
