Kaley Cuoco's 'Lip Sync Battle' performance is Ludacris

"Penny is NOT here, baby."

Kaley Cuoco shed her Big Bang Theory persona definitively in her Lip Sync Battle performance. The sweet, blonde star performed a rendition of Ludacris' Move B---- on the show and it is ludicrous in more ways than one (be warned, clip contains some NSFW language):

We prefer her costume to her Lip Sync enemy Josh Gad, who went full-Trump to perform I Touch Myself for ... reasons.

The pair's episode airs Thursday at 10:00 p.m. ET on Spike.
