Will Ferrell channeled his inner Beyonce in epic fashion as part of greatest lip-sync battle Jimmy Fallon has staged yet.

On Sunday's post-Super Bowl broadcast, Fallon challenged Get Hard co-stars Ferrell and Kevin Hart to two rounds of battle. Ferrell, bump-and-grinded his way through "Drunk in Love." "You can't un-see that!" Fallon joked, before giving his best rendition of Kelly Clarkson's "Since You've Been Gone." Hart, meanwhile, slow-jammed to John Legend's "All of Me," reducing his object of affection, Ferrell, to fake tears.

For the second round, Ferrell chose "a contemporary classic from Adele Dazeem," as he (fake) belted "Let It Go." But Fallon then upped the ante (and ripped his pants) by performing Dirty Dancing's "Time of My Life" with surprise guest partner, Drew Barrymore. Closing out the competition, Hart took on halftime performer Katy Perry's "Roar."

As if the lip-syncing battle wasn't enough star power for one night, Fallon gathered Christina Aguilera, Sam Smith, Carrie Underwood, Ariana Grande and others for an a capella version of Queen's "We Are the Champions." Check it out:
