There really is only one Oprah Winfrey.
She just posted a fraud warning on Instagram, saying someone is using her name to get you to pay money for access to Oprah-licensed social media accounts. O says, "Don't believe it, don't give up any of your bank accounts or personal information to anyone posing as me or anyone else, for that matter."
Oprah also channeled her inner soprano just to drive home the point.
