If you're like us and value your sleep, you probably nodded off into your Ambien dreamland before the party started on post-prime time TV. Don't worry; we've got you covered. Here's the best of what happened last night on late night.

Is anyone else wondering how Lady Gaga and Tony Bennett started working together? We're right there with you. This unlikely duo hit up "The Tonight Show" for a quick performance, and then Lady Gaga explained how a stripper inspired her to get old school with her act. Priceless!


The Sony hack has taken a turn for the completely crazy, but David Letterman still has a sense of humor about the situation, and decided to read some hacked emails on "Late Show." There's an jingle, there are a few LOLs, and there are a bunch of completely hilarious (fake!) notes like "Nicholas Cage says the script's terrible and he's in."


Speaking of the Sony hack, FOX's Megyn Kelly stopped by "Jimmy Kimmel" to give her take on the studio's decision to pull The Interview, and called it "deeply troubling." She also thinks the American people need to take the situation into their own hands by downloading the film, while Kimmel thinks we should start putting Kim Jong-Un in every movie ever.


On a lighter note, Jimmy also had a proposal go down on his show! This host with the most let an audience member go on a scavenger hunt around Hollywood Boulevard, and yes, it ended in her husband (dressed as Elmo, of course) popping the question. Adorable!

Finally on "Conan," Jason Schwartzman chatted about how he hates smoking pot, and naturally he was completely charming about it. Turns out he gets slightly paranoid, and one time wrote out his will on a newspaper due to thinking his heart was going to explode.
