Jennifer Lawrence [1] insists she's a terrible singer [2], but that didn't stop her from singing on Saturday Night Live [3] with Josh Hutcherson and Liam Hemsworth during host Woody Harrelson's monologue this weekend. It wasn't just any old song, though — the Hunger Games: Mockingjay — Part 1 [4] costars put a new spin on Taylor Swift [5]'s "Blank Space." As Harrelson points out, it's been nearly 25 years to the day that he first hosted SNL in 1989, so it's only appropriate that he'd pick a song from Swift's 1989 album. Although you'll recognize the melody, the lyrics have been completely rewritten to give us a wild history lesson. Check out the silly ensemble performance, below!
