Robert Pattinson And Kristen Stewart Lock Lips As 'Breaking Dawn' Filming Starts!

OME, is that Kristen Stewart and Robert Pattinson kissing? In public, with no inhibitions, as though it was the most natural thing in the world? The two lovebirds have been spotted cozying up all weekend in Rio de Janeiro, which can only mean one of two things: They're finally willing to address their off-screen romance in public, or filming on "Breaking Dawn" is finally under way.

Unfortunately, all evidence—from Kristen's Bella Swan hair extensions to her prop wedding ring to the camera crews surrounding them—confirms that it's the latter, but a "Twilight" fan can dream, can't she? The two were all dolled up and looking gorgeous as Bella and Edward on Sunday for some pre-honeymoon romps in Brazil, which means only one things: Isle Esme filming is just around the corner!

According to Twilight Examiner, the cast flew to Rio to film three major scenes: an airport scene where Bella and Edward arrive in Brazil, a taxi cab scene that brings them to a marina and then a boat scene where Edward drives Bella to Isle Esme, their honeymoon destination. Considering the happy couple were just married, we won't be surprised to see many kissing scenes in this portion of filming!

One of the most marked differences from previous "Twilight Saga" shoots is just how adult Bella looks. Yes, she is a married woman now and 18, but still, goodbye jeans and long sleeves! We're loving how classy KStew looks as honeymoon-bound Bella and hope that this shift to more adult clothing is consistent for the rest of the film.

Our big question from these photos, though, is where is Edward's wedding band? Bella's is pretty noticeable on Kristen's left hand, but we can't seem to spot Edward's. Since we know that whole vampires-allergic-to-silver rumor is just a myth, we can't seem to come up with any explanation for its absence. Not starting this marriage off on a very good foot, Mr. Cullen.

Are you glad that "Breaking Dawn" filming is finally underway? Why do you think Rob's not wearing Edward's wedding band?
