Jonah Hill hosted Saturday Night Live for the third time this weekend, and The Wolf of Wall Street actor brought along a little surprise: his costar. Leonardo DiCaprio made a cameo during Hill's monologue, and I can almost guarantee it's the best thing you'll ever see. See, Hill gets nervous about appearing in the public eye, so DiCaprio calms him down by re-creating one of his infamous scenes from Titanic. Yes, Hill gets to be Rose. No, you've never been this jealous of Jonah Hill before.
