Glee Stars Lip-synch "Last Friday Night"

Now this is what fun, fun, fun, fun looks like. YouTube sensation Keenan Cahill got to lip-synch “Last Friday Night” with Glee stars Dianna Agron, Darren Criss, Jenna Ushkowitz and Harry Shum Jr. Serious hair flipping, crazy dancing and fake swimming? Definitely winning.
Keenan says he’s got another video with the Glee cast coming up. Can you guess what song he’ll lip-synch with which Gleeks? Got any requests? Tell us in a comment!
