Streep and Hathaway will reprise their roles as Miranda Priestly and Andy Sachs, while EW previously exclusively reported that Adrian Grenier won't return.

In addition to Streep, original "The Devil Wears Prada" stars Anne Hathaway, Emily Blunt and Stanley Tucci are returning for the sequel, 20th Century Studios confirmed to ABC News in June. Oscar winner Kenneth Branagh will also star in the film as Miranda's new husband, according to 20th Century Studios.

Anne Hathaway famously debuted a full fringe hair transformation in the original The Devil Wears Prada, so it's no surprise that her character Andy Sachs is getting a new style for the sequel. While filming the highly anticipated flick in New York on Monday, Hathaway was spotted with a brand new set of hair highlights.
