The Who's That Girl World Tour is the second concert tour by American singer-songwriter Madonna. The tour supported her third studio album, True Blue(1986), and the soundtrack Who's That Girl (1987). It was Madonna's first world tour, reaching Asia, North America and Europe. Madonna's 1987 film Who's That Girl was a box office failure, but its soundtrack proved to be a commercial success. Warner Bros. felt that they could encache on Madonna's success further and they sent her on a world tour. Musically and technically superior to her previous Virgin Tour, the Who's That Girl Tour incorporated multimedia components to make the show more appeal.
