Celebrities on Facebook?

Are there any celebrities (Selena Gomez, Justin Bieber, Demi Lovato, Debby Ryan, ETC.) that have Facebook accounts? And not those ones where you like them, I am talking about accounts you can friend. I am a really big fan of Ariana Grande, Justin Bieber, and Selena Gomez so do they have facebook accounts? I know everyone has asked this question but I wanted a new answer. So, let me know! Thanks :) - Jamie
