HARRY: "SECRET" TROUBADOUR GIG TONIGHT

Harry-mania overtakes West Hollywood tonight, with a just-announced show at the legendary Troubadour–known as a launching pad for the likes of Elton John, The Eagles and Linda Ronstadt. Styles’ performance at the intimate, 500-seat venue caps a busy week in L.A. for the Columbia singer-songwriter, who just wrapped a week-long residency on CBS’ Late Late Show With James Corden. The show sold out just minutes after Styles announced the date on his Twitter feed.
