Remember when Jennifer Lawrence and Amy Schumer were on a jet ski together? Those were the days.

It turns out they're not just vacation buddies and squad colleagues. They're also writing a screenplay together that they'll star in. Lawrence told the New York Times that she emailed Schumer after seeing Trainwreck to say, "I don't know where to get started. I guess I should just say it. I'm in love with you." Also casually mentioned in the Times interview? The new movie that "flowed" out of them. They'll play sisters. They've written 100 pages so far. They talk on the phone everyday. See, kids? This is why it's important to read the newspaper.
