Real life BFFs Courteney Cox and Jennifer Aniston are together again! As reported several weeks ago, Aniston is stopping by Cox's hit sitcom 'Cougar Town' for a guest-starring role--and PEOPLE has some of the first images.

One image shows Cox and Aniston sitting side by side, looking stunning, on a porch. The second photo features Aniston sitting on a bench with a cute little white dog.

Aniston plays Cox's psychiatrist Bonnie in the sitcom's season premiere episode that airs on September 22. Though she's only signed on for one episode, show creator Bill Lawrence says, "We're very intentionally implying that it's a therapist Courteney has been using for a while and we're certainly not going to make it like they'll never see each other again. So I'm crossing my fingers that if she has a good time it'll happen again."
