Boone told the Clarion-Ledger that she pleased by the response.
“I originally only wanted 200 people to sign and we have a thousand," Boone told the Jackson newspaper. "It's crazy."
The prom is Friday at the Columns in downtown Memphis. Boone and Ellenberger said they will attend.
The DeSoto County School District released a statement that said seniors are “nominated for prom royalty by their peers.”
“School administrators were asked about a couple that wanted to be Prom King and Prom Queen. Students were informed that individuals, not couples, are elected to the court,” the statement said. “Using an online nomination process, students select one male and one female student to represent the senior class. This process ensures that both males and females can participate and serve on the court."
