NEW YORK - Jennifer Aniston will return home to NBC, the TV network where she became a breakout star on the hit sitcom "Friends."

She's currently filming a guest appearance on the network's "30 Rock," Aniston publicist Stephen Huvane confirmed Friday.

There were no immediate details on the role Aniston will play — as herself or a fictitious character — or the episode's planned air date.

The New York-based series, which begins its third season in October, stars Tina Fey and Alec Baldwin in a behind-the-scenes, sometimes self-directed spoof of a television network and the huge corporation that owns it. The show has won a modest but devoted following, and critical raves. Awards include Golden Globes, a Peabody and last year's Emmy for outstanding comedy series.

With its show-biz slant, it has become a haven for guest appearances by big names from entertainment — even politics, including Al Gore.

Another of the six-member "Friends" troupe, David Schwimmer, had a "30 Rock" guest shot last season.

Since "Friends" concluded its highly successful 10-year run in 2004, Aniston has concentrated on films, including "Friends with Money," "The Break-Up."
