A new promo for the series -- which returns on July 9 -- shows Bieber and Azalea lip synching for probably the first time ever (zing!), but they're not alone. Alison Brie also does what looks to be a pretty stellar rendition of "Bang Bang," Terrence Howard takes on his "Empire" wife Taraji B. Henson with a disco-tastic take on "Brick House," and Will Arnett goes back to his roots with "Everything is Awesome."
Oh, and did I mention that the girls from "Broad F--king City" are joining in on the fun? No, I did not. But I will now.
