"She did a Q&A Not long ago, I think it was one of them assumptions ones and it was someone saying she’s bisexual and she said “no I’m not bisexual I get asked this a lot, I have nothing against being bisexual I know people who are from the LGBT community but I’m not” or something along them lines.
Also another hint of her being bisexual.. her recent caption on her instagram. “Even if the boys and girls don’t” you would typically just put “boys” if your straight and now she’s added the girl part."
I cut a little bit out because its long but its the gist. So she might be, she might not..only she really knows.
