Are Jaden Smith and Ezra Koenig working together? That is the first question that comes to mind after a glance at the Vampire Weekend frontman's Twitter. Koenig casually tweeted a picture of the pair along with the caption, "things are bubbling in the sea beneath 14th street." Of course, that could be a coy reference to the hard-to-make-out sketch he shared along with it. But it wouldn't be entirely surprising if they were collaborating on music. Last year Koenig flexed his hip-hop side on a remix of iLoveMakonnen's "Down 4 So Long." Plus, he has a lot of free time at the moment. Late last month, Koenig gave a status update on Vampire Weekend's follow up to Modern Vampires of the City, saying, "I’m not in a rush to dive into making an album because I feel like I want the next album to kinda feel like a new era anyway, so I’ve been kind of enjoying this time just chilling."
