Well this is awkward!

Robert Pattinson arrived at LAX for a flight to London yesterday, and the actor couldn't avoid questions from photographers about his ex-girlfriend Kristen Stewart being a lesbian! The Twilight star was even asked if her sexuality "explains" things about their relationship, which is basically meant to imply that she was never serious about their relationship because she secretly wanted to be with a woman, hence why she sabotaged the whole thing by cheating.

His moody actress former love has been spending every waking moment with her "close pal"/girlfriend Alicia Cargile, and they've even been seen holding hands on numerous occasions, but she has yet to address the rumors they're in a romantic relationship.

R-Patz kept quiet on the subject as he made his way through the terminal, but he couldn't help but crack a knowing smile as he waited for the elevator. You have to see his reaction!
