Kaley Cuoco Performs Ludacris Raps In Lip Sync Battle Preview

The Big Bang Theory's Kaley Cuoco is unleashing her inner Ludacris on this week's episode of Lip Sync Battle.

The actress is squaring off with Frozen's Josh Gad, who was already seen impersonating Donald Trump in his performance, and she chose to go all-out gangster mode. Lip Sync Battle co-host was pretty shocked to see the transformation from Penny to on-stage rapper.

Check out the preview.

Kaley Cuoco and Josh Gad's episode of Lip Sync Battle airs Thursday at 10 PM ET on Spike TV.
