letterman-oprah*Years of friction between Oprah Winfrey and David Letterman ended on Dec. 1, 2005, when the daytime queen decided to bury the hatchet in order to promote “The Color Purple” opening on Broadway.

On Thursday, Aug. 1, she’ll make her second visit to the “Late Show,” CBS announced today. This time, she’ll be promoting the Aug. 16 release of “Lee Daniels’ The Butler.” She stars in the film as Gloria Gaines, wife of Cecil Gaines (Forest Whitaker), who, as a White House butler, eyewitnesses notable events of the 20th century during his tenure. The film is based on the real-life account of Eugene Allen, who served as a White House butler during eight U.S. presidencies, from 1952 to 1986.

Prior to her 2005 appearance, Letterman had expressed his long-standing desire to have Winfrey as a guest on the show. With fans and media cheering on, Letterman famously escorted Winfrey after the interview taping to The Broadway Theatre, directly across the street from the Ed Sullivan Theater, to the “Color Purple’s” premiere.
