I have the worst memory: Courtney Cox

London: Actress Courtney Cox says she hardly remembers anything of her past achievements.

The 47-year-old relies on friend Jennifer Aniston to recall their days on hit show "Friends".

"I have the worst memory. I could not tell you what we did in `Cougar Town` last year. I don`t remember anything. Jennifer Aniston can remember every episode of `Friends`, what we were wearing, what we said, what we were doing while we said it. I don`t remember any of it," showbizspy.com quoted Cox as saying.
