Is Miley Cyrus A Lesbian?

Miley Cyrus has been doing everything she can to make people see her as a grown up from racy video to smoking from a bong.  Now there have been some really racy photos of Miley Cyrus released but the one posted above makes us wonder maybe Miley is a lesbian?  The photos were released after her concert last night and her assistant that she is lying on seems really to be into her.  What do you think is Miley just fooling around or is she lesbian?
