Rachel's sisters on the sitcom Friends, Jill and Amy Green, were portrayed by Reese Witherspoon and Christina Applegate respectively. Originally, Rachel was only supposed to have one sister, which was Jill. However, Amy was added in season 9, leading some to speculate that there was tension between Aniston and Witherspoon, but both actresses denied this. Witherspoon's role wasn't cut due to a feud, but because it wasn't necessary for Jill to return. Witherspoon had scheduling conflicts when the showrunners wanted her back for season 9 and again for season 10. Both actresses remember their roles fondly, and they are good friends now.
