Madonna is in danger. According to The Daily Star, the pop singer has hired more than 400 bodyguards after receiving death threats from Balkan fanatics. The bodyguards were meant to assure the diva’s Sticky & Sweet Concert in front of 30,000 fans in Belgrade, Serbia on Monday night.

It seems that Madonna has arrived in disguise and surrounded by her bodyguards after receiving threatening messages before her first performance in Belgrade. Madonna’s representative Liz Rosenberg refused to comment the nature of the threats.

The singer got so scared that she will keep the guards to accompany her for the Romanian concert tonight.
