If you haven't got a mirror on hand, you use whatever reflective surface is available to check your makeup. And if it's a gigantic knife blade, so be it.

Emma Roberts wields perfect lipstick and a pointed blade in the new teaser for Scream Queens. We don't see much else, but really, do we need to?

Watch the first teaser for Ryan Murphy's Scream Queens

Scream Queens is the latest series from Glee and American Horror Story creator Ryan Murphy. The show is supposed to be a comedy horror, so it seems like Murphy is mashing up his greatest hits. The first season of the series — or anthology, as Murphy puts it — will be about a sorority house plagued by a masked killer.

In the first teaser released for the show, a bubbly blonde sorority type blows a bubble that gets popped by a knife and a wash of blood. In the second one, called "Chanel Bubblegum" Roberts exits a sorority house and blows a bubble that turns into a freaky demon face. Between that and the new teaser, it seems like Roberts is preparing to reprise her bad-girl vibes from American Horror Story.

Watch the new teaser, called "Chanel Knife":

The show premieres this fall on Fox.
