As “American Idol” bid farewell to fans with the final episode on Fox, the show’s Season 5 runner-up Katharine McPhee danced her ass off over on Spike.
The “Scorpion” star took on Jason Derulo on the hit fake-singing competition show, “Lip Sync Battle,” and proved she wasn’t a sweet and innocent girl next door anymore.
McPhee turned the heat up out of the gate with a booty-jiggling rendition of “Shake It Fast” by rapper Mystikal, which clearly impressed host LL Cool J.
However, it was Derulo’s bare-chested performance of “Pony” by Ginuwine that made Chrissy Teigen want to jump into his saddle and ride him.
McPhee responded by channeling her inner stripper — swinging on a pole in a satin bustier and getting thrown onto a fur coat-strewn bed by a ripped male dancer, ironically to the tune of one of Derulo’s own hits, “Want To Want Me.”
“It’s a whole new Katharine tonight,” LL Cool J marveled.
Derulo counter-attacked by getting “Freaky” and transforming into Rick James, complete with sparkly spandex and plenty of hip thrusts in tight leather pants.
After a night of raunchy performances, the audience had the tough job of picking a winner — which was ultimately McPhee.
“I never win ever — I was on a show that I lost,” she said, referring to “Idol,” adding: “I finally won something!”
“Lip Sync Battle” airs Thursdays at 10 p.m. on Spike.
