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.

"Pretty Little Liars" star Lucy Hale was on "Conan" Tuesday night, and she talked about how her sexy Cosmo cover embarrassed her father. It wasn't the photo as much as the cover words. Her dad saw the headline "Best Sex Ever" and he thought that was her interview. He texted her to say she looked great but he wasn't too excited about the articles. (He probably read them all, though.) Lucy also talked about "Pretty Little Liars," which is Conan's "neighbor" in the studio lot. PLL has a pink golf cart that's all decked out. On the show, they say "bitches" a lot, and they put it on the back of the golf cart. They got a complaint from Warner Bros. human resources so they had to censor it, and blocked out part of the "b-tches." Rainn Wilson was on "Conan" and he went off on the foodie obsession in big cities. "Have we not learned a lesson from history, Conan? What was the last great civilization that gorged and vomited over and over again? ... The Romans!" He said it's just wrong to fetishize food that way. But then he discussed the octopus pastrami he had for his birthday, which was exquisite. Kevin Costner was on "Jimmy Kimmel Live," discussing how he just turned 60, and his daughter gave him a really thoughtful gift. He talked more about his kids, and his career. Jimmy asked if he'd give advice to a newbie on the scene like Eddie Redmayne, who was nominated for an Oscar. Kevin got to meet Stephen Hawking, whom Eddie played in "The Theory of Everything." It was kind of an awkward meeting, from Kevin's retelling, but apparently Stephen was a big Whitney Houston fan and the entire point of him randomly stopping by Kevin's house was to get intel on Whitney. Interesting! Jimmy noted that someone should've just told the guy about e-mail, 'cause that would've solved it. Eddie Redmayne was also on JKL, and Eddie shared his own story of meeting Stephen Hawking. He didn't ask Eddie about Whitney but Eddie said he's one of the most charismatic men you'll ever meet, and definitely a ladies man. Eddie also shared his excitement at being part of the 2015 awards circuit. "A Most Violent Year" star Oscar Isaac was on "Late Show" with David Letterman discussing his roles in the upcoming movies "X-Men: Apocalypse" and "Star Wars Episode VII: The Force Awakens." He said "Star Wars" comes out first, but he can't say anything about the movie or they'll descend and execute him on site. But Dave still played a scene from the new movie. Except not really. Whitney Cummings was also on Dave's show, talking about how she keeps busy shooting all her canceled shows. She's joking, but she also joked about how she's become a professional talk show guest, just going on different shows to promote her upcoming appearances. "The Tonight Show" and "Late Night with Seth Meyers" are still on repeats, but David Letterman pulled double duty, hosting his own show and also acting as a guest on "The Late Late Show," which was guest hosted by Regis Philbin. Dave shared a classic memory from his show, tied to a musical guest.
