Washington: Courtney Cox has announced that her best friend Jennifer Aniston will make a guest appearance on her new show, 'Dirt', in which Cox plays the editor of a weekly celebrity magazine.

"We talk about it all the time - what kind of character she should play? Should she play herself or should we write some great thing for her?," Contactmusic quoted Cox as saying.

Cox stunned fans on Tuesday (9Jan07) when her character masturbated with a vibrator in the show. In the climactic scenes, the 42-year-old enjoys a one-on-one orgy with the sex toy, pleasuring herself twice in one session.

The series also sees Courtney's character's in the hit show; Lucy, use a stun gun on one man she lures into her bed.

The show is but two weeks old and has scored solid ratings last week with 3.4 million people watching the premiere in the US. (ANI)
