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.

Will Smith has been breaking out his vintage rapping skills on the talk show circuit, and he busted out his classic hit "Summertime" on "Jimmy Kimmel Live." It was, in a word, super 90s. By which we mean super awesome, partially because Will was wearing a white turtleneck for the entire performance.

Ice T swung by "The Tonight Show" to get some things off his chest in a game called Sound Off, and apparently he has a lot of feelings about "50 Shades of Grey." We believe his exact words were "boring, it could have been on Nickelodeon" and "how about Shade of Black, that's all you need."

Christina Aguilera is best known for being a songstresses, but turns out she also does an amazing Samantha Jones circa 'Sex and the City' impression. Check out Xtina slaying on "Late Night" below!

Ever wonder what Melissa Rauch got up to before "The Big Bang Theory?" Apparently she spent her time chillin' in the basement recreating musicals as an eight-year-old, including the song "Tits and A**." And yes, she brought a video of her performance to "Conan."
