The Friends beauty and Loos - who claims she had an affair with soccer superstar David Beckham when she worked as his personal assistant - are in talks with series creator and star Jennifer Saunders to appear in a Hollywood special.
An Absolutely Fabulous source told Britain's NEW! magazine, "Jennifer Saunders has written a list of the stars she would like to make cameo appearances.
"Jennifer thinks a brief appearance from Rebecca would have great comic effect."
Aniston is reportedly thrilled with Saunders offer as she has been a fan of the long-running show for several years.
