Kristen Stewart and Robert Pattinson boarded a helicopter yesterday in Rio de Janeiro. The Twilight costars got down to some serious kissing on Sunday, as they shot Breaking Dawn's honeymoon. They may well be on their way to Casa em Paraty to film secluded island scenes, as it can only be accessed by boat or helicopter. Kristen had Rob as her flying companion this time, after travelling from LA to New Orleans last weekend solo. They've enjoyed their down time together while in Brazil, as well as putting in hard work and long hours.
