Anne Hathway did more than just get on a giant wrecking ball on Thursday’s episode of “Lip Sync Battle.” In a heroic effort, she took down her “Devil Wears Prada” co-star Emily Blunt by giving the world a DGAF middle finger ala inspiration, Miley Cyrus.

Blunt brought out what she thought were the big guns — heart-shaped balloons, flower power shtick, etc. — to perform Janis Joplin’s “Piece Of My Heart,” but she couldn’t beat Hathaway, who could probably tour as Cyrus right now. The crowd chanted “Hathaway” and Blunt conceded.

And here’s the first round, during which Hathaway performed Mary J. Blige’s “Love” and Blunt took on Blackstreet’s “No Diggity.”
