Well, err.... we really don't know. But there's a rumor to that affect!

The Mirror reports that Kate Moss will star along with Stella McCartney, Linford Christie and Colin Jackson in a one-off Absolutely Fabulous special to benefit Sport Relief on March 23.

An unnamed source said Kate was excited to be on the show, is a real fan and always quotes it with her mates.

"She sees the parallels between her life and Patsy and Eddy's, and she finds it really funny," they told The Mirror. "When she got the script, she squealed with delight. She thinks it's brilliant, and she likes having a giggle at her own expense."

Kate, shown above at Stella McCartney's London Fashion Week presentation, would surely make a hilarious addition to the AbFab gang!
