Oprah Winfrey recently learned she has a half-sister she never knew about.  A woman, identified only as Patricia, appears on the show today and explains that she felt it was important that she talk to Winfrey herself and not let someone else tell her.

Patricia was given up for adoption by Winfrey's mother, Vernita Lee, shortly after her birth in 1963. Both women get understandably emotional on today’s show and Oprah says that one of the most impressive things about the woman's discovery that the two are half-sisters is that the woman never tried to take advantage of her or sell her story.

The "Oprah Winfrey Show" is in its 25th and final season. Watch the show today on WCCO at 4pm.
