Alison Brie And Jason Sudeikis Are 'Sleeping With Other People' In This New Red Band Trailer

Might as well face it: they're addicted to love.

Whether you've seen "When Harry Met Sally" or not (but if not, what are you even doing, go see "When Harry Met Sally"), you've surely asked that age-old question at least once in your life: can men and women really be friends?

The answer is yes, duh, but sometimes those friendships evolve into something a little more. Enter the premise of "Sleeping With Other People." In the case of Lainey (Alison Brie) and Jake (Jason Sudeikis), the duo slept together in college, then reconnected as BFFs as adults after running into one another at a meeting for sex addicts. But is there something more there?

In the hilarious red band trailer for the movie, watch Lainey and Jake roll on Molly, spoon and digitally pleasure a Snapple bottle. Intrigued? You should be.

"Sleeping With Other People" hits theaters September 11.
