Amy Green is coming back to see her sister Rachel and her "Friends."

Christina Applegate will reprise her role as Rachel's (Jennifer Aniston) egotistical younger sister in an episode of the long-running NBC sitcom's final season. Amy will be called upon to babysit Rachel's daughter Emma, presumably after Rachel has exhausted all other options.

The episode is scheduled to air during November sweeps.

Applegate scored an Emmy nomination for her first guest appearance on "Friends" last November. She also starred in the NBC series "Jesse" several years ago, and in FOX's "Married ... with Children" for its entire 10-year run.

Her feature credits include "The Sweetest Thing" and the upcoming films "Wonderland," "Surviving Christmas" and "Grand Theft Parsons."
