Oprah Winfrey finds sister she didn't know she had

Oprah Winfrey says she's learned she has a half-sister she never knew about.

Winfrey announced on "The Oprah Winfrey Show" that aired on Monday that a Milwaukee woman named Patricia discovered that the two were half-sisters.

The woman says she had been searching for years for the identity of the mother who gave her up for adoption in 1963. She says she learned in 2007 that Winfrey was her half-sister. On her program, Winfrey says she learned about Patricia last November.

Winfrey says she was 9 years old and living with her father when her mother had the daughter and gave her up for adoption. She says she never even knew her mother was pregnant.

Winfrey says the two met on Thanksgiving day.
