Mia Wasikowska, Robert Pattinson film make-out scene on 'Maps to the Stars' set

Photogs caught Mia Wasikowska getting hot and heavy with Robert Pattinson in Los Angeles on Wednesday night. But don't worry "Twilight" fans, it's not for real.

The two young actors were filming a make-out scene for their upcoming film, "Maps to the Stars,", David Cronenberg's satirical drama about Hollywood. Wasikowska stars as a pyromanic just out of a sanatorium, while Pattinson plays a limo driver and aspiring actor.

According to E! News, Wasikowska and Pattinson "were spotted laughing and joking with one another" in between cuts.

Pattinson, 27, split with Kristen Stewart earlier this year, while Wasikowska is dating "Social Network" star Jesse Eisenberg.
