Competing on American Idol and singing her heart out on Smash has prepared Katharine McPhee for this pivotal musical moment. 

While competing against "If It Ain't Love" crooner Jason Derulo for Lip Sync Battle, the 32-year-old actress dropped it to the ground in honor of her selected song, the millennium hit "Shake It Fast" by Mystical. Fun fact: Pharrell Williams has uncredited vocals on the track. 

Clad in a simple white v-neck t-shirt, a pair of skin tight black leather pants and a think gold chain, McPhee two-steps around the stage as she faux raps the songs' famous rhymes. 

At one point, she makes it rain when she reaches into her shirt for a stack of cash that she proceeds to launch into the air.

The routine gets even sexier when at one point, she drops to the floor and pushes her behind into the air. 

The sultry routine was cheered with vibrant applause and two jaw-dropped looks from Derulo and host LL Cool J

Close your mouths, gentlemen!

The full episode airs Thursday, April 7 on SpikeTV.
