While speaking to MediaVillage for an interview published on Saturday, the Dirty Dancing star recalled being cast as Mindy in Friends. In her guest-starring role, Grey played the former best friend of Rachel (Jennifer Aniston), who married Rachel's ex-fiancé. Grey recounted her excitement turning to fear after spending time on the show's set. "When I did it, I had such bad anxiety because they kept changing the script.” Jennifer Grey / MediaVillage.
