The New Moon promotional juggernaut has begun in earnest – and Kristen Stewart and Taylor Lautner reported for duty in Brazil on Sunday.

The pair – whose relationship as Bella and Jacob is central to the Twilight sequel – joined forces for a press conference to promote the movie at the Grand Hyatt Sao Paulo Hotel.

Meanwhile, their co-star Robert Pattinson kicked off his promotional tour thousands of miles away in Japan.

The heartthrob was greeted by hundreds of screaming fans at Narita International Airport in Chiba on Sunday.
