Kaley Cuoco got ludicrous during her recent Lip Sync Battle performance.

The Big Bang Theory actress took the stage at Spike’s Lip Sync Battle to lip sync and dance to Ludacris’ “Move B****.”  Host Chrissy Teigen was shocked by Cuoco’s performance and asked her where her Big Bang character Penny was.

“Penny is not here, baby!” Cuoco exclaimed at the end of her performance.

Cuoco battled her The Wedding Ringer co-star Josh Gad. Gad performed “I Touch Myself” dressed as Donald Trump. Cuoco’s co-star and ex-boyfriend Johnny Galecki made an appearance during his performance, and he even shared a kiss with Gad on stage.

Cuoco, who filed for divorce from Ryan Sweeting in September, was rumored to be dating Galecki again.

Other notable battles include Channing Tatum channeling his inner Beyonce and Joseph Gordon- Levitt performing a Janet Jackson song.

Lip Sync Battle airs Thursdays on Spike, and Cuoco’s episode premieres Jan. 28. The show was recently renewed for a third season.
