There's finally some real, photographic evidence that Kristen Stewart and Robert Pattinson are dating!
While they usually avoid being seen together unless it's on the red carpet for a "Twilight" premiere, the couple was very cuddly at the Cannes after-party for the debut of Kristen's latest flick, "On the Road."
The two were snapped kissing (on the lips!) on the balcony at the bash in one photo ... and in another Rob is seen kissing Stewart on the forehead. Everybody now: Awwwwww!
The sighting comes after Rob hit the red carpet to support his girlfriend's new movie earlier in the day ... though the two walked down the arrivals line solo.
