Rumors are flying about Oprah Winfrey's "surprise" reunion today, and according to a biographer, the special guest could be from Winfrey's family.
Winfrey biographer Kitty Kelley told a local blogger that the reunion is with a sister Winfrey's never known.
Winfrey's father, Vernon, told the Associated Press he doesn't "have the least idea of what she has in mind," and Harpo Productions isn't saying.
A commercial for today's episode says the reunion is a "miracle" that may be a family secret.
We'll find out soon enough.
