U.S. comedy “30 Rock” will receive Jennifer Aniston, 39, in a guest appearance. The TV show will also have Tiny Fey and Alec Baldwin in the cast. The comedy will show behind the scenes of a TV network and the important corporation which owns it.

Also David Schwimmer, who played the role of Ross Geller in “Friends,” appeared in the 30th episode of “30 Rock.” Since success and filming of “Friends” ended in 2004, Jennifer Aniston focused mostly on films such as “Friends with Money” or “The Break-Up.”

The 39-year-old actress became famous in 1994 when she interpreted the role of Rachel Green in the sitcom “Friends.” She won an Emmy Award and a Golden Globe Award for her 10 years job with the show and many of Hollywood’s gates opened for her.

Most of the films she played in were comedies such as “Bruce Almighty,” “Rumor Has It” or “Along Came Polly.” But her personal life came to surface when she married Brad Pitt on July 29, 2000.

The media considered their marriage as a good example in Hollywood but they split up on January 7, 2005 when rumors about Brad Pitt and Angelina Jolie had already started. Since then, the actress has been linked with actor Vince Vaughn, model Paul Sculfor and singer John Mayer.

Leaving her personal life away, Jennifer Aniston has been listed by “Forbes” magazine as the 10th richest woman in the entertainment industry for 2007. She owns nearly $110 million.
