Selena Gomez has joined the cast of Universal and Good Universe’s “Neighbors 2.”

She will star alongside Seth Rogen and Zac Efron in the “Neighbors” sequel, along with Chloe Moretz. Gomez proved her rowdy college movie chops in “Spring Breakers.”

“Neighbors” was a surprise hit with $269 million in worldwide grosses. Rose Byrne is set to reprise her role, with Nicholas Stoller returning as director.

The original revolved around a couple whose lives are turned upside-down after declaring war on the fraternity that moved in next door. The sequel’s plot is unknown, though sources say a sorority could be the couple’s problem this time.

Gomez’s involvement in the film broke when fan photos revealed that she was on set. While details surrounding her role are unknown, her sorority girl-esque costume (a tight pink dress) suggests her character’s involvement with the Greek system.

Rogen, Evan Goldberg and James Weaver will produce under their Point Grey Pictures banner. Andrew Jay Cohen and Brendan O’Brien will serve as executive producers alongside Good Universe’s Nathan Kahane and Joe Drake. Writers include Cohen, O’Brien, Rogen, Stoller and Goldberg.

Gomez, who is repped by WME and Brillstein Entertainment, most recently shot Paramount’s “The Big Short” and James Franco’s “In Dubious Battle.”

“Neighbors 2” bows in theaters May 20, 2016.
