Meryl Streep made a rare comment about her life as a grandma. The Devil Wears Prada 2 star, 76, has six grandchildren under the age of 10, but she doesn't necessarily identify as a "cool grandma," she shared on the Thursday, April 30, episode of Jimmy Kimmel Live! "I don't know," Streep responded to host Jimmy Kimmel when he asked whether the kids think she is cool. "I think I'm a little like Miranda Priestly as a grandma. Because I like the rules, dear," the Oscar winner quipped, referring to her taciturn magazine editor character in the Devil Wears Prada franchise.
