The actress hit the set yesterday to film a cameo appearance for season four of the show - and it seems she was quite a hit with the cast!
Taking to Twitter to share a snap with the Sex and the City star, Chris Colfer exclaimed his love for the songstress, asking Glee creator Ryan Murphy - 'Can we keep her?'.
'I love her - I love her! Can we keep her? RT @MrRPMurphy: First scene! Kurt and Isabelle,' he gushed.
Sarah Jessica Parker will play Vogue editor Isabelle for her cameo appearance in the show, who becomes a mentor for Lea Michele's character Rachel Berry.
And that's not all. Earlier in the week, Mr Murphy told fans that not only would SJP play a member of the Vogue team in the show, but that the magazine's US editor would be helping with her costume choices.
'Guess who's helping us with Sarah Jessica Parker's costumes on GLEE? The amazing Anna Wintour!' he wrote.
Now we are excited.
Earlier this month Kate Hudson hit the set to film her stint in the show. The actress will play Lea Michele's dance instructor Cassandra July in the upcoming series four of the show - and will reportedly appear in as many as six episodes.
