Katharine McPhee faces off against Jason Derulo on this week’s Lip Sync Battle, and she’s not messing around. The American Idol runner-up chose to perform Mystikal’s “Shake It Fast” and she totally committed to the tune.

In a preview from the upcoming episode, McPhee wears a white T-shirt, tight leather pants, and a gold chain necklace as she pantomime-raps the lyrics, drops it to the floor, and even makes it rain with a handful of cash. “Bend over girl, show me what you workin’ with,” Mystikal raps, and the Scorpion star obliges, eliciting a hilarious reaction from Chrissy Teigen.
