Robert Pattinson and Kristen Stewart's rumoured relationship is still to be confirmed, and yet we already have video footage of a supposed lover's tiff between the pair.

The Twilight saga co-stars were filmed apparently 'aving words as they returned to their hotel in a haze of flashbulbs.

The couple had just enjoyed a three-hour dinner date in Vancouver (click here for the pictures), where they are currently filming part three of the vampire series Eclipse.

According to Splash, Rob is seen apologising to Kristen, who snaps: "Can we just wait for these people to go up?!"
