Lady Antebellum will perform their first European concert on Aug. 11 at London's O2 Shepherd's Bush Empire. "Need You Now" has already been a Top 10 hit in the U.K., while the trio's current single there is "I Run to You." (In the U.S., their follow-up single to "Need You Now" was "American Honey.") Tickets go on sale Friday (July 23). According to tour dates posted on the band's official website, the London performance will take place between their final concert on Tim McGraw's tour on Aug. 7 in Toronto and before the Illinois State Fair on Aug. 13 in Springfield, Ill.
