Zac Efron and his starlet girlfriend, homeowner Vanessa Hudgens, were snapped at LAX yesterday.

They have returned from their whirlwind tour of Europe and the U.K. where they were promoting the stuffing out of their new flick, High School Musical 3: Senior Year.

Their co-star Ashley Tisdale recently claimed that she’s never had any romantic interest in Zac, and vice-versa.

That must have sparked some conversation on the plane home from London.

Or some uncomfortable silence judging by their faces in these photos.
