Former "Friends" co-stars Courteney Cox and Jennifer Aniston are thick pals in real life too.

When Aniston won the Showest best female of the year award this month, Cox and her husband David Arquette took out a full-page advertisement on the Hollywood Reporter magazine to congratulate her, Sky News reports.

The tribute said: "Congratulations Jennifer... Your enormous heart makes you an incredible actress and a beautiful friend. We love you. Courteney, David and Coco."
