Looks like it's Rachel Bilson premiere season! She and her costar/something or other Hayden Christensen posed at the red carpet screening of Jumper at the 4th Dubai International Film Festival today. She looked great in her sassy turquoise number, earning a red carpet gold star to go along with her cleaning up on Fab's best sidewalk style of 2007 poll. Hayden, on the other hand, broke his mini streak of hot by looking a little too disheveled — blame the jet lag? Hopefully, these two will get a little cozier on the red carpet (if they are really dating) as this promotional tour soldiers on.
