Liam Hemsworth has been busy promoting his new movie Mockingjay — Part 2, but even he has time for a few laughs. The Australian actor stopped by Late Night With Seth Meyers on Wednesday night and talked about everything from his appearance with Miss Piggy [1] on The Muppets to Jennifer Lawrence [2]'s infamous clumsiness [3]. He even revealed that, contrary to popular belief, Jennifer doesn't actually fall on purpose; she's just "terrible at walking." He then goes into hilarious detail about how his costar is actually much more accident-prone than anyone realizes. See him crack up in the video above, and then check out his swoon-worthy red carpet pictures [4].
