Kaley Cuoco Channels Her Inner Britney Spears on Lip Sync Battle

After seeing Josh Gad dressed as Donald Trump during his Lip Sync Battle preview, it didn't seem like anything could top it — but Kaley Cuoco came pretty close! The actress channeled her inner Britney Spears as she slithered around with a live python snake for an epic performance of "I'm a Slave 4 U." Although her rendition was pretty spot-on, Josh's surprise appearance with Kaley's The Big Bang Theory costar and ex Johnny Galecki stole the show. Watch the full video above, and then check out Beyoncé's surprise appearance during Channing Tatum's episode.
