Barbara Walters to interview Oprah Winfrey

Hourlong special set to air Dec. 9 on ABC.

Oprah Winfrey is set to have a sitdown with veteran journalist Barbara Walters about the end of her afternoon talk show.

The hourlong special will also touch on memorable moments during Winfrey's 25-year run, the Associated Press reports. ABC announced Thursday that Walters will conduct the interview at Winfrey's home and Harpo Studios in Chicago.

Winfrey announced she would exit her daytime talk show earlier this year to focus on her new cable network OWN.

The interview will air Dec. 9 on ABC, with Walters' annual spotlight on the most fascinating people of the year airing right after.
