Winfrey joined best friend Gayle King and company for O You! The day long seminar, organized by O Magazine, is lead by some of Oprah's biggest pals!
Oprah's arrival was a surprise for everyone attending except BFF Gayle King.
"And there is a surprise at the end of the day but I am not telling," King said.
Apparently even event organizers did not know Oprah's plans.
