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.

David Letterman had Julia Roberts on "Late Show" Wednesday night, and he did what a lot of guys have probably wanted to do for decades: He planted a big wet kiss right on her famous lips. They'd done it before on the show - several times - and they showed clips of Julia and Dave smooching over the years. But this was their last kiss, since Dave is leaving as "Late Show" host and May 20 is The End. So they walked out onto the stage - Julia in her sexy letterman jacket - and they had a final kiss. So sweet. But before leaving, Julia gave him a speech: "I just want to say, David Letterman, I love you and I thank you for all of the joy, and the laughs, and the intelligence you have brought to us for 33 years." He said he loved her back and they hugged. Funny, you can see through the clips how much he's aged over the years but she just stays beautiful. Good genes or ...? Before the kiss, Julia discussed her very first appearance on Dave's show -- to promote "Mystic Pizza" -- and she didn't want to go on the show because Dave had dismembered other actresses in her peer group. But it turned out well and she was on the show 26 times. Dave wanted to know why she had that perception of him, that he might instantly know her IQ and rip her apart like a samurai. Julia: "Because I think stupid people annoy you." Dave: "Well, I think that answers my problem with self-loathing." Haha. Paul Shaffer was also Dave's guest, and to have him there talking about working with music legends really brought it home. The show is ending.Rebel Wilson was on "The Tonight Show" and she and Jimmy Fallon played "The Whisper Challenge," which is always fun. Rebel asked if they had to take off clothes if they lost. Strip Whisper Challenge! Haha.
In her sit-down interview, Rebel talked about working on an early TV show in Australia. She and Jimmy discussed her big opening scene in "Pitch Perfect 2." She said she did her own aerial stunts, training for five weeks to do a 45-second routine in the film. Rebel also talked about having a fear of heights after falling off a roof. (!) James Marsden, Kat Graham, and Brandon Flowers were on "The Late Late Show with James Corden." James showed off an old soda ad Kat did, and Kat got up to do a little Salsa. James Marsden wouldn't dance with her, but Corden got up and gave tons of sass. James and Kat both love the '90s and Kat talked about staying at Prince's house. James Marsden also discussed a meeting with Justin Bieber at the Met Ball. Corden and Marsden competed over their love for JB. Elizabeth Banks was on "Jimmy Kimmel Live," talking about being the boss on set when she's directing a movie, like "Pitch Perfect 2." Elizabeth chatted about foreign press and there were some German jokes. Comedian Marc Maron was also on JKL and he told Jimmy he cast an actor just to get back at a Twitter troll. Tatiana Maslany was on "Late Night with Seth Meyers" and Seth talked about her Emmy snub for "Orphan Black," and what it's like when she plays just one character as opposed to all the clones. She also discussed helping to build an Igloo and how she had a street named after her.
