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.

Christina Aguilera was on "The Tonight Show Starring Jimmy Fallon" Monday night, and Jimmy had "The Voice" coach play "Wheel of Musical Impressions." Xtina had to mix artists like Cher (with whom she worked in "Burlesque") with songs like the Folgers Coffee jingle. She was good! Christina really went for it when she got Britney Spears (her fellow Mouseketeer then pop star rival) paired with "This Little Piggy." Pretty obvious that was not just a random selection, but dagnabbit - Christina nailed it. For once, Jimmy was completely outshined at one of his own games. He gave her a standing ovation! Christina also sang Shakira well. The woman can sing. "Survivor" host Jeff Probst was on "The Tonight Show" and explained why he stopped doing pranks. He pranked Dave Grohl with a fake Adam Levine Gmail account - and it backfired. Genuinely great story. Basically, Jeff insulted some nice person's mother. Hilarious. Kobe Bryant was on "Jimmy Kimmel Live" Monday night to talk about his rumored retirement, his documentary, his injury, the Lakers losing streak, his disappointment with his teammates reactions (you have to see his face in that clip), Bill Clinton and Michael Jackson. He also answered some viewer questions. Chrissy Teigen was also on JKL, talking about Oscar night. Her husband John Legend just won an Oscar, and John was there backstage, so she wasn't sure why she was the one on JKL. She also did a (sad) magic trick since she just joined a special magic group. Stephen Amell of "Arrow" was on "Late Night with Seth Meyers," and the ladies in the audience just loved him. Seth's show is hitting its one-year anniversary, and Stephen had tweeted that one of his goals for 2015 was to be on this show. Stephen shared a story about being at the Golden Globes in 2013. He sat by himself at the "Big Bang" table and it was awkward. Good interview, though. Interesting guy. The great Mary J. Blige was on "Late Night," talking about guest starring on "Empire" and how her friend Taraji P. Henson might be a little too much fun. Dame Helen Mirren (BOW TO HER) was on "Late Show with David Letterman," discussing the Oscars, "Selma" and equal pay for women. Dave also had Daytona 500 winner Joey Logano, 24, on his show. "Conan" featured the cast of "It's Always Sunny in Philadelphia" - you can see a bunch of videos on the TeamCoco site, but here's the story behind the "Lethal Weapon" episode. Charlie Day argues that it wasn't blackface, it was "Danny Glover face." Plus, they insulted North Korea years before "The Interview" and no one cared.
