Courteney Cox is working on a sitcom for herself, Lisa Kudrow and Jennifer Aniston.

The 'Cougar Town' actress is keen to work with her former 'Friends' co-stars again after remembering how much fun they used to have together when they all appeared on Jimmy Kimmel's talk show last month.

Courteney wants to direct a pilot staring herself, Jen and Lisa as middle-aged women who have kids by artificial means.

However, Jennifer - the only one of the actresses not to have children - is said to be a bit uncertain about the show's subject matter.
