Lip Sync Battle got super hot this week as two stars got unexpectedly hot and heavy — OK, maybe it was less "hot" and more "hilarious"!

The Comedians star Josh Gad put on his best Donald Trump impression in a political spin on The Divinyls hit "I Touch Myself," even stripping down to skivvies made of cold, hard cash — but it was a surprise appearance by a Big Bang Theory star that stole the show!

Yup, that would be Johnny Galecki he's making out with, dressed as a mariachi singer. On a horse.

Making this even more hilarious is that Gad's opponent in the competition was Kaley Cuoco, Galecki's Big Bang Theory costar and rumored girlfriend!

Cuoco denies the former flames are dating again after her divorce from Ryan Sweeting, but they were all over each other at the People's Choice Awards. Public speculation after the show aired led Cuoco to caption Instagram pics of the two "#mydate" "#notdating."

We haven't seen any clips of Cuoco's performance, but you can see who wins — and if she has anything up her sleeve that could possibly top Gad and Galecki's crazy kiss — on Lip Sync Battle Thursday on Spike TV.
