Spike's Lip Sync Battle is the gift that keeps on giving.

In the latest face-off, John Krasinski took on Anna Kendrick. And even though Kendrick gets paid millions for this kind of work in the Pitch Perfect franchise, Krasinski proved he was quite the contender by doing his best Justin Timberlake impression for *NSync's "Bye, Bye, Bye" (complete with marionette choreography, natch).

Kendrick then showed she isn't above fighting a little dirty, dragging Krasinski's wife (and former Lip Sync Battle contestant) Emily Blunt into it. During her rendition of One Direction's "Steal My Girl,'" Kendrick busted out a romantic slideshow of Blunt and ripped off her jacket to reveal a photo of the two of them enclosed in a heart.

Well played, Kendrick. Well played.

To close off the competition, Krasinski took on Tina Turner's "Proud Mary." He started off slow, casually strolling around the stage in a suit. But once the tempo picked up, The Office alum stripped off the suit to reveal a sexy silver dress and turned that ish out!

But Kendrick wasn't about to let Krasinski's drag-a-licious performance one-up her. Following her expertly choreographed performance of Jennifer Lopez's "Booty," J.Lo herself emerged. And if that isn't the ultimate mic drop, I don't know what is.
