Kristen Stewart  was in her standard travel uniform as she arrived at an airport in Paris on Sunday. She was coming from a visit home to California, where she met up with her Snow White and the Huntsman costars for a photo shoot. Kristen posed with Chris Hemsworth and Charlize Theron  for an upcoming magazine spread, though we've yet to learn which publication. Kristen is gearing up for a busy Spring with the release of her action-packed movie, and apparently there may be some other big news. A Variety film editor tweeted  about seeing On the Road writing, "OTR is finished. Took 1 year to edit, and is very, very good. According to a discerning and in-the-know viewer, it's so good that . . ." The tweet sparked tons of rumors, including a popular one that he is implying OTR will open this year's Cannes Film Festival in May.
