Hundreds of screaming fans packed the outdoor concert stage to get a glimpse of Trey Songz on Jimmy Kimmel Live! on Wednesday (July 25). The R&B crooner, whose fifth album, Chapter V, arrives August 21, closed out the show with a performance of “Heart Attack,” the Rico Love-penned lead single. Backed by a live band, Tremaine delivered a so-so showing on the late-night show; vocal rest and lemon should always be part of his ministry before performing live. Just sayin’.
