Celebrity Farrah Can't Get Enough By People Staff Published on December 28, 1998 12:00 AM Share Tweet Pin Email More than two years after her “Late Show with David Letterman” appearance in which she slurred her words and appeared distracted, Farrah Fawcett is coming back for more. Oct. 13 she’ll sit in the seat opposite the sarcastic host in order to plug her CBS movie “Silk Hope.” (It airs Oct. 17.) No proper explanation for Fawcett’s behavior on the June 1997 show was ever offered, but the show’s producer, Rob Burnett, says that Dave has no plans to embarrass the former “Charlie’s Angels” star when she returns.
