But does this mean there's going going to be a Robsten reunion in France?! Sadly, it does not, because as a source tells E! News, the exes "won't be there at the same time."
Rob, 27, has two movies premiering at Cannes this year: The Rover, on May 18, and Maps to the Stars, on May 19. Kristen, 24, stars in Clouds of Sils Maria, which premieres May 23, but she won't be arriving early just to take in the sights: She'll be busy shooting American Ultra!
Still, though, if Kristen and Rob had crossed paths in Cannes, they most likely would've been civil. Last fall a source told E! News the Twilight co-stars and former real-life loves did have "lots of animosity [between them] after the split," but have since "moved on and gradually gotten over it."
Don't get ahead of yourselves, though! An insider also said at the time that while the couple formerly known as Robsten "are cordial now" with each other, their friends "honestly believe they will not get back together."
And it looks like those pals have been right so far.
