Saunders, who penned the book for the Spice Girls musical Viva Forever, and Lumley, a Tony nominee for La Bete, returned to the screen for a special three-episode 20th anniversary season that launched last Christmas.

The 30-minute episode, which finds Eddy and Patsy prepping for a star-studded Olympic week, will air at 10 PM ET. It aired in the U.K. July 23.

Here's how it's billed: "Edina and Patsy are well known for having their fingers on the pulse of the nation. As the sound of the approaching Olympiad reaches deafening proportions, Eddy is surprised that it is all about to start. She has rented out her house to a Hollywood A-lister, but she’s still living in it, as is Saffy, Mother and Bubble. Patsy tries to get into Eddy’s body-suit to look suitably great for the A-listers, with disastrous results. Eddy feels age is catching up with her and invitations are no longer coming her way. Fashion designer Stella McCartney has even kicked her out of her shop! And to make matters worse, her ex-husband Marshall and his girlfriend Bo show up on her doorstep to for a place to stay during the Olympic Games. But somehow before the Olympic flame has been lit, Edina and Patsy find themselves inside Olympic Stadium. One can only imagine what happens next."

"Absolutely Fabulous" debuted in 1992 on BBC and traced the booze-fueled antics of ill-equipped PR "mogul" Eddie Monsoon and her chain-smoking best friend and fashion editor Patsy Stone. An uptight disapproving daughter, absent-minded mother and completely incompetent assistant figure into the series that ran through 1996 and returned for a 2001-2004 run.
