It will be only the second time Oprah Winfrey has visited David Letterman‘s late-night talk show, following the long-in-the-works and much-publicized appearance in December 2005 after years of public bickering (and wooing) by Letterman. Winfrey is making her second-ever appearance August 1, the CBS show said today. Eight years ago, Winfrey’s appearance coincided with the red-carpet premiere of The Color Purple on Broadway; after her appearance, Letterman escorted her across the street to the opening. This time, Winfrey is promoting her new film Lee Daniels’ The Butler, which hits theaters August 16.
