Kristen Stewart: Peep My Boyfriend!

Twilight leading lady Kristen Stewart and her Sky High boyfriend Michael Arangano keep their heads down from snapping shutterbugs as they arrive at LAX airport in Los Angeles on Monday evening.

Kristen, 18, recently hinted on Ryan Seacrest‘s radio show that Twilight‘s sequel, New Moon, could possibly start filming as early as March 2009. Director Catherine Hardwicke even reinforced Kristen‘s statement to MTV.

Catherine shared, “I would say that the film could be finished by the end of 2009, if not the beginning of 2010; cameras could be rolling in about five months. We spent about a year and three months getting ['Twilight'] ready, between writing the script and casting. We could probably do things a little bit faster this time, but who knows? It depends. And sometimes you can do things really fast. You can get two editors on, and you can just zip through.”
