When it was announced that Emily Blunt would be stepping into Julie Andrews’ “practically perfect” shoes for an upcoming remake of their iconic Mary Poppins film, we were overjoyed.

However it seems as if Disney may have added yet another spoonful of sugar to Mary Poppins Returns, as it has now been reported that Blunt will be joined on set by her Devil Wears Prada co-star, Meryl Streep.

Which is just supercalifragilisticexpialidocious news, isn’t it?

According to Variety, Streep would be taking on the role of Topsy Turvy, better known to fans of the P. L. Travers books as Mary Poppins’ cousin.

The character did not feature in the 1964 film starring Julie Andrews and Dick Van Dyke, which Travers famously hated – but it has been reported that the role will require Streep to sing, much like she did for her award-nominated performance in Into The Woods.
