A top Croatian pop star has appealed to the public to return or destroy private pictures of her enjoying a lusty sex romp which appeared on the Internet this week. Severina Vuckovic told local newspapers the pictures and an 11-minute video of her making love to an unidentified dark-haired man had been stolen from her private collection. The pictures showed up on an internet site June 1, 2004 and immediately became the hottest news in the former Yugoslav republic, where 32 year-old Vuckovic had previously been an icon of righteous and religious modesty. Croatian pop star Severina Vuckovic is seen performing at the Opera House in Rijeka in this undated file photo.
