NEW YORK (AP) — Jazmine Sullivan knows she and Eric Church are completely different artists, but the R&B star said she’s excited to join forces with the country singer to give fans a memorable rendition of the national anthem at Sunday’s Super Bowl. Sullivan and Church have been working hard at rehearsing since it was announced they would sing together at the Raymond James Stadium in Tampa. One of Sullivan’s idols, Whitney Houston, has arguably the best performance of “The Star-Spangled Banner” at a Super Bowl game. Sullivan said she’s a big fan of Houston’s version, and she recently learned that Houston was a fan of hers, courtesy of Missy Elliott.
