"Ok, I need to say something. My sister is being viciously attacked. And let me assure you - it is all bullsh*t," Vance DeGeneres, a former Daily Show correspondent and Ellen's older brother, wrote on Facebook Tuesday night. "I put up a simple statement yesterday that said 'I stand by Ellen.' Only a handful of my Facebook 'friends' responded to it. If you don't support Ellen, then you don't support me, so please unfriend me. I'm sick and tired of my sister being attacked. She always has - and always will - stand against bullying of any kind. She's a smart, strong woman who has made a positive difference in the world. And to my friends who did respond with support for Ellen and my family, thank you so much. It means a lot." ALSO: Ashton Kutcher and Diane Keaton are the latest celebrities to stick up for Ellen on social media.
