The two are contractually obliged to be appear side by side on the red carpet.
A source told The Sun: "RPatz is in pieces but the Twilight love triangle storyline is nothing without him and Kristen.

Kristen and Robert both met on the set of the Twilight films and have been dating for about three years.
Rupert directed Kristen in Snow White And the Huntsman.
