Oprah's 'family secret': a long-lost half-sister

Some daytime talk-show hosts have to bring the drama in from outside, but Oprah Winfrey's past is the gift that just keeps on giving.

ABCNews.com reports that that the "bombshell family secret" Oprah's announcing on today's show (4 p.m., Channel 6) is a younger half-sister named Patricia whom her mother gave up for adoption in Milwaukee, Wis.,  in 1963, at a time when the future talk-show host was living with her father in Nashville, Tenn.

"I had no idea my mother was even pregnant." Oprah said, according to ABCNews.com, whose full report can be found here.
