Pictured: Courtney Steiner (in pink) and Carly Levy (in navy).Courtney Steiner and Carly Levy have made history, becoming the first same-sex couple to be elected prom royalty at their high school and possibly in the entire state of Pennsylvania.The two were voted in last week at Pennridge High School, located in Perkasie, in Bucks County just north of Philadelphia.“I think that it shows how inclusive and progressive we’re becoming,” Steiner told the Courier Times, a local newspaper.But at first the two 18-year-old seniors weren’t even sure they’d be allowed to run, given that students elected prom royalty have traditionally been kings and queens.
