Emily Blunt channeled every ounce of her inner Janis Joplin during the April 9 episode of Lip Sync Battle, absolutely slaying her performance of "Piece of My Heart."

Indeed, the Into the Woods actress went full-on Janis during the number, donning an oversize fur jacket, messy hair and even the iconic singer's trademark pink-tinted sunglasses as she (silently) roared out a stadium-worthy performance of the classic hit.

Of course, her Devil Wears Prada co-star/Lip Sync Battle nemesis Anne Hathaway was there to egg her on slash simultaneously rip her apart (all in good fun, duh) during the routine. And because Blunt was duking it out against Hathway's "is this real life?" performance of Miley Cyrus' "Wrecking Ball" (which you can relive here because it was just that amazing), the stakes were higher than ever.

Ultimately, though, Anne Hathaway dominated — because, really, there is nothing better than watching Princess Mia/Ella Enchanted/Fantine come in like a wrecking ball and crush her performance left, right and sideways. Was there really ever any doubt that she was going to completely wreck the competition? Ha. (Although, maybe she should still give her trophy to Meryl Streep as Miranda Priestly since we are going with all of the movie references here.)

You can also watch Emily Blunt and Anne Hathaway get a little bit of that R&B flavor during the show, also battling it out with Hathaway's performance of Mary J. Blige's "Love" as Blunt goes all Pitch Perfect on us with Blackstreet's "No Diggity." Check out those performances in the video below.
