Oprah Winfrey settled her "feud" with David Letterman by appearing on his show in 2005. Now Letterman is returning the favor.

Winfrey s traveling to New York to tape several shows the week of Sept. 10, and Letterman has agreed to be one of her guests. The appearance will be a rare foray outside the "Late Show" studio for Letterman, who outside of awards ceremonies generally doesn't appear on other people's shows.

The New York-based Winfrey shows, which will tape at Madison Square Garden, will also focus on the sixth anniversary of the 9/11 attacks, news reports say. She's likely to interview survivors and others affected by the attacks about how they've coped and tried to bring about positive changes since then.

Her interview with Letterman, which will kick off "The Oprah Winfrey Show's" 22nd season on Monday, Sept. 10, likely won't be that serious. Winfrey, of course, is a long-standing Letterman obsession, as he spent years comically courting her to appear on "The Late Show" when he wasn't having fun at her expense.

The pursuit finally paid off in 2005 when Winfrey, whose production of "The Color Purple" was playing across the street from Letterman's Ed Sullivan Theatre, agreed to appear on "The Late Show." The two also taped a Super Bowl commercial last year.
