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.

Taylor Swift was on "The Tonight Show" Tuesday night, and Jimmy Fallon told her he was really upset because she dances all the time now, but that used to be their exclusive thing. They were "famous Jumbotron dancers." Jimmy shared "random" Jumbotron footage showing the two of them going for it. Love how they flip the popcorn every time. Funny bit. The people in the background are the best. Taylor and Jimmy also cemented their new BFF status by drawing each other without looking.

Kristen Bell was on "Jimmy Kimmel Live" to talk about Dax Shepard's 40th birthday and their two young daughters, Lincoln and Delta. They almost forgot Dax's 40th b-day because they were in that new baby haze. Kristen said Dax named their second baby Delta, without knowing there was a woman named Delta Burke. He thought he made up the name for a girl. Kristen also talked about how she was such a stubborn kid as a child and insisted everyone call her Smurfette. Then Matthew. Then Annie. They settled on Annie and some people still call her that. Jimmy Kimmel also video-chatted with Britt from "The Bachelor." Jimmy said his wife and her friends all want Britt as The Bachelorette, and she seemed very happy about the idea. Did Britt have any idea that Carly did not like her? She only found out about the puppet thing when she watched the show back. Britt said she wasn't lying about her Iowa reaction. She does shower. And she's still working as a waitress, except now people don't tip her so much because she's "famous" and they assume she was well-paid to be on "The Bachelor." Dakota Johnson was on David Letterman's show and she told Dave that her mom, Melanie Griffith, told her to tell Dave that she (Melanie) loves Dave. Melanie was on the show a lot and she brought Dave handcuffs one time. Dakota: "So, are you my dad?" They discussed the origin of her name. She thinks her parents stole the name from friends' parents who were also about to have a baby. She was supposed to be named Ruby but Don Johnson thought Ruby Johnson sounded like a stripper's name. Jack McBrayer and Triumph the Insult Comic Dog were on "Conan" to promote their new show, and Conan O'Brien called out the puppeteer as the worst "f--king puppeteer" ever." Triumph shared his censored NBC jokes and there are also web-only Andy Richter jokes. "The Walking Dead" star Lauren Cohan was also on "Conan," talking about her first Hollywood job as a waitress. She was in over her head, and had one customer who was a real jerk. When he left the table to use the bathroom, his own friends told her to pretend to have a nervous breakdown when he came back. She went for it with a full meltdown - and someone from CBS casting was actually in the restaurant and told her to call. Lauren also said she wants a zombie apocalypse Fitbit to count all her steps on TWD. Conan thinks the zombies should wear them, since all they do is walk. Lauren thinks zombies should advertise the Fitbits. Brilliant! Taraji P. Henson was on "Late Night with Seth Meyers" and Seth decided to audition for "Empire" on the spot. He wants to be in Cookie's posse. He said her father inspired her character. Matthew Perry was also on Seth's show and he talked about how he almost turned down "Friends" in 1994 because he was committed to another show called "LAX 2194" about futuristic LAX baggage handlers. Haha.
