The notoriously private, Robert Pattinson and Kristen Stewart, were spotted on a date the other night! They attended a Marcus Foster concert in London and it seems like they had a blast. Even though Kristen has tried to keep mum about the fact that she's dating Robert, Rob recently revealed that his relationship with Kristen is "obvious." Maybe now that the Twilight saga is starting to die down they'll finally admit they're together! (celebuzz)
