In addition to their lips, John Krasinski and Anna Kendrick are using every tool in their musical arsenal – including Jennifer Lopez – in the next Lip Sync Battle.

In this clip, Krasinski, 35, begins singing Proud Mary before suddenly ripping off his suit and shimmying in a short, silver fringed frock that would make Tina Turner proud.

And if you think that’s good, Lopez, 45, struts out to accompany Kendrick, 29, on what looks like a Pitch Perfect duet.

Her surprise appearance even throws Krasinski, who yells, “What is happening?”

Let’s see if these can top Anne Hathaway‘s unforgettable performance of “Wrecking Ball” by Miley Cyrus when she faced off against Krasinski’s wife Emily Blunt, who turned in her own solid performance of Janis Joplin‘s “Piece of My Heart.”

Considering Battle executive producer Krasinski and Blunt, 32, invented the game, we think his chances are strong.

Lip Sync Battle airs Thursdays (10 p.m. ET) on Spike.
