Chris Colfer and Sarah Jessica Parker

Sarah Jessica Parker is putting her most fashionable foot forward once again — this time on Glee as Kurt's new mentor, Isabelle.

In this behind-the-scenes photo courtesy of Twitter-happy co-creator Ryan Murphy, fans can get an early first look at the show's new dynamic duo. Not only does Parker, a fashion icon since her days rocking Carrie Bradshaw's Manolo Blahniks on Sex and the City, look radiant, but Chris Colfer is seen sporting a modern (and much more aerodynamic) new 'do. Elvis would be proud!
