After watching Rob Pattinson and real-life love Kristen Stewart lock lips for the cameras, there's no denying that these two have chemistry both on and offscreen.

The two Twilight stars made out on the beach in Brazil for a steamy scene for the upcoming film, Breaking Dawn. We love how they have to do several takes! Kissing Rob over and over again ... such a hard days work.

Twilight producers say despite the film's sexiness, the rating will remain PG-13. Breaking Dawn: Part 1 hits theaters on November 18, 2011.
