A rally for school equality is proving to be a star-studded affair as Grammy Award-winning singer Jennifer Hudson is set to headline the event at Cadman Plaza in Brooklyn, N.Y. next week. Hip-hop legend DJ Jazzy Jeff and "The Man" singer Aloe Blacc are also slated to spin and speak as well, respectively.

“I’m standing for education equality because every child deserves access to a great school,” said the Dreamgirls actress, who's expected to sing at least four songs, according to the New York Daily News.

An estimated 15,000 parents, students and educators are expected to fill Cadman Plaza in Brooklyn on Oct. 7 to "call for an end to New York City’s separate and unequal schools."

The "Stand for School Equality" rally will also bring education leaders, elected officials, staples in the community and student performers to join the celebrities on stage in the rally for justice.

Activists are also planned to cross the Brooklyn Bridge into Manhattan until they reach the steps of City Hall to hold a press conference.

This won't be Aloe Blacc's only good deed this week. The "I Need A Dollar" singer will also perform to fight poverty at the Robin Hood Rocks Festival on Friday (Oct. 2) in New York City.

DJ Jazzy Jeff isn't new to activism either. The famed producer is known for boycotting the Grammy Awards with his counterpart, Fresh Prince aka Will Smith, in 1989, after they refused to televise the two getting their award. Fresh Prince and DJ Jazzy Jeff's "Parents Just Don't Understand" was the first rap song to win a Grammy Award.
