Cue the sound of 10 million teen hearts breaking.
Kristen Stewart and Robert Pattinson have remained mum about their rumored romance for years, but finally, there's definitive proof that the pair are officially on.
Following the premiere of Pattinson's latest film, 'Water for Elephants,' co-starring newlywed Reese Witherspoon, the hunky Brit was spotted smooching his 'Twilight' co-star in the back of their chauffeured car.
The pair have spent plenty of time locking lips on screen, but this is one of the first times the pair have been caught practicing their PDA without any vampires watching.
Despite past rumors that Pattinson was sowing his wild oats, the actor recently revealed that he's not afraid to commit.
"Life is not black and white ... [but] there is one thing I never understood: why people cheat," Pattinson told Vanity Fair Italy.
"My parents met when my mom was 17 and my father 25, they are still together and seem very happy. I grew up believing that you can be together all of your life."
