Whoever told you Jennifer Aniston is a lesbian is wrong. Angelina Jolie is the one that was bisexual for a really long time. She even had a girlfriend at one time before she gave up licking and dildos.
So what if she grows up to be a lesbian like Jennifer Aniston?
I think you and J should mind your own business. So what if she's a dyke? or FTM like Chaz? What is it to you?
