Oprah Winfrey recently learned she has a half-sister she never knew about.  O introduced Patricia, on the show Monday

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

The "Oprah Winfrey Show" is in its 25th and final season. You can see highlights from the show at Oprah's website
