I think it's safe to say that any diehard Friends fan will agree that Reese Witherspoon — who played Rachel's sister, Jill — was one of the best guest stars to ever appear on the series.
Sadly, Reese's character only appeared on two episodes (and, honestly, it felt like they could have brought her back).
Well apparently, she could have returned. While promoting their new series, The Morning Show, Reese revealed to Jennifer and all of us that she had been asked to guest-star again on Friends, but turned it down:
Reese Witherspoon (@ReeseW) reveals that she was asked back to #Friends but declined. Unlike Jennifer Aniston, she did not enjoy performing in front of a live studio audience when she played Aniston’s sister on the show.
According to Reese she was "too scared" to reprise her role 'cause she didn't like performing in front of a live audience.
To which Jennifer — finding out this news — had this reaction:
Reese added that she disliked doing a live-taping so much, that she has never done it since.
While it would have been great to see Reese back on the show again, it did open up the door for another amazing guest star on the show: Christina Applegate. Reportedly, when Reese was unable to reprise her role (or didn't want to?), the writers created the character of Amy, who was just as great.
