'Frozen's' Josh Gad vs. 'Big Bang's' Kaley Cuoco on 'Lip Sync Battle' [VIDEO]

Kaley Cuoco and Josh Gad went head to head on Lip Sync Battle Thursday night. The Big Bang Theory star and the voice of Frozen’s Olaf gave it their all, with Cuoco performing a little Ludacris and Britney Spears and Gad lip synched to Divynls and Whitney Houston.

Gad, best known for Frozen, Love & Other Drugs and The Wedding Ringer, performed Whitney Houston’s "I Wanna Know" with a giant bow in his hair, but really had the crowd going when he performed The Divynls hit song "I Touch Myself" while dressed as Donald Trump.

Gad stripped and straddling a wrecking ball before Cuoco's The Big Bang Theory co-star Johnny Galecki rode in on a donkey wearing a sombrero. Gad and Galecki then made out on stage, poking fun at Trump's stance against illegal immigration. Cuoco laughed and stated, "I have no words for what just happened. I am shocked."

Kaley Cuoco then took it back to the early 2000s and did an awesome version of Britney Spears' song "I'm a Slave 4 U," complete with a huge albino snake. For those not familiar with Cuoco, she has appeared on 8 Simple Rules on the big screen in Lucky 13, Picture Perfect and Virtuosity. She divorced her tennis star husband Ryan Sweeting in September 2015, less than two years after they were married.

The actress later shed her cute image and busted out some sexy dance moves to rapper Ludacris' song "Move B*tch."

Co-host Chrissy Teigen appeared shocked, saying, "I watch Penny ever week. Where is Penny?"

Cuoco replied, "Penny is not here, baby."

In the end, Gad won the battle even thought Cuoco did an awesome job. There just was no way to overcome the funny of Gad as Trump.
