Is Kristen Stewart a lesbian?

Kristen Stewart is a lesbian? If not for this picture, we can say that Miley Cyrus and Kristen Stewart are just good friends, but the male hairstyle of the protagonist of Twilight is suspect. Unless this is a trivial photomontage. However, it is considered unlikely by Lazy Gossip Girl: no sentient being could miss time with such nonsense for the sole purpose of discrediting a very famous girl, even if envy is a very powerful force.
