The sexiest woman in music (at least, that's what a recent survey in a US magazine revealed), Beyoncé Knowles, is heading to Australia to kick off her world tour. The Showgirls star and former Destiny's Child frontwoman will perform hits from her most recent LP, 2006's B'Day, in Sydney, Brisbane, Adelaide and Melbourne. Beyoncé's visit follows her recent trip Down Under with boyfriend Jay-Z on his own tour. The 25 year-old singer's latest single, "Listen", is taken from the Showgirls' soundtrack and is released on Monday February 19. Tickets to her shows go on sale Friday February 16.
