Jennifer Aniston shared that she is naturally a brunette, which is why she considers her iconic blonde hairstyle to be "fake." In a Jan. 6 Instagram video, Jennifer answered a question about whether she would ever go brunette and simply answered, “I am brunette.” Her former ‘Friends' costar Courteney Cox then appeared in the clip and jokingly draped her own darker hair over Jennifer’s head to show what she’d look like with the color.
