With a rumored subtitle of "Sorority Rising," the sequel to "Neighbors" is clearly going to need plenty of killer females to face off against its original cadre of dudes.

And now they've got a new one who comes with serious star power: Selena Gomez has officially joined the cast.

There's no word on just what Selena is doing on the "Neighbors 2" set -- in fact, her involvement in the movie was never even officially announced -- but she's definitely there, and she's definitely looking fabulous in a hot pink bandage dress and giant feathered earrings.

She's also accompanied by an entourage of girls in white dresses and flower crowns who look like they've escaped from a May Day festival, or maybe the "Outlander" credits, so take that as you will.

"Neighbors 2" also stars Chloë Grace Moretz along with returning cast members Zac Efron, Seth Rogen, and Dave Franco. The movie will be in theaters in 2016.
