Rob And Kristen Still Going Strong, Ready To Start Filming On Breaking Dawn

Kristen Stewart and Robert Pattinson arrived in LA last night, flying in from Montreal where Stewart is filming On The Road -- and where Pattinson was visiting his Twilight lady.

The pair arrived around 7 pm and didn't do much to hide from photographers however, the two split up when they first spotted the snappers, so as not to be seen together in the same frame. Why??!!

Rob, Kristen and the rest of the vampire crew are set to start filming the fourth and fifth installments in the Twilight Saga this fall in Louisiana and in Vancouver. The first half of Breaking Dawn, based on Stephanie Meyer's book series, is set for release in November 2011. Academy Award-winning director Bill Condon will direct both parts.

But back to RPatz and KStew last night ... why so coy with us, guys? You're together, you want to be together, and everyone wants you to be together -- why not let us have it?!
