When ‘The Devil Wears Prada 2’ began filming, the return of Meryl Streep, Anne Hathaway, Emily Blunt, and Stanley Tucci was enough to send the fashion world into a nostalgic frenzy. However, now, the internet is in full-blown speculation mode after Sydney Sweeney was spotted near the set.

Meryl Streep, who plays Runway editor-in-chief Miranda Priestly, was first pictured on set last Wednesday, wearing a beige Lanvin coat, a purple silk top and a cognac Gabriela Hearst leather pencil skirt. Stanley Tucci has been spotted on set too, reprising his role as Nigel.

Here's why fans are buzzing with the idea that Sydney Sweeney might be making a cameo in "Devil Wears Prada 2."
