“Devil Wears Prada” rivals Anne Hathaway and Emily Blunt were reunited on Thursday night — and this time they were armed with microphones.

The actresses were the latest stars to compete on Spike’s “Lip Sync Battle,” the new hit spin-off from Jimmy Fallon’s “Tonight Show” game.

After revealing mock behind-the-scenes footage of her rehearsal, “Into the Woods” actress Blunt mimicked Janis Joplin in a fur coat, colored glasses and waving flowers around to perform “Piece of My Heart.”

“I feel like I was at the Woodstock after-party,” host LL Cool J said.

“I was just trying to crush Anne Hathaway up here,” Blunt explained.

The British actress later took on a totally different persona when she rapped “No Diggity” by Blackstreet.

Hathaway revealed backstage that she had made a Voodoo Doll for Emily, before stripping down on stage for a raunchy reenactment of Miley Cyrus‘ “Wrecking Ball.”

“Which is harder … lip syncing, riding the wrecking ball or winning an Oscar?” asked LL. “Only one of them feels natural and it’s the frigging wrecking ball,” the “Les Miserables” actress replied.

The impressive aerial performance earned Hathaway the winner’s belt, which “color commentator” model Chrissy Teigen presented.

“Lip Sync Battle” was announced in November and has Fallon teaming up with executive producers John Krasinski, Stephen Merchant, Casey Patterson, Jay Peterson and Rick Schwartz. Beth McCarthy-Miller of “Saturday Night Live” serves as director.

Last week’s premiere, featuring Dwayne Johnson taking down Fallon, scored record ratings for Spike and drew 2.2 million total viewers — the largest viewership for an unscripted series debut in the network’s history.

“Lip Sync Battle” airs on Spike on Thursdays at 10 p.m. ET.
