With a host of Bollywood stars like Salman Khan, John Abraham, Mallika Sherawat, Zayed Khan, Esha Deol, Kareena Kapoor performing live, Rockstars has been one rocking show till now. But it didn't start quite well.

We hear that while departing for the show Mallika arrived in a burkha at the airport with her brother Vikram and another male companion and refused to take it off when officials at the counter asked her to show her face for identification before boarding.

Says an eyewitness "She refused to lift her burkha till her manager sorted it out."

Even when a photographer began to click pictures of the trio, her male companion approached him and threatened to manhandle him and his camera equipment.

According to him, "I clicked pictures of the other stars too and they were all extremely polite and cooperative. But when I began to take pictures of Mallika, her friend approached me and warned me to stop clicking or else he would break the camera."

On Saturday, the Boardwalk Hall in Atlantic City was filled to capacity too where Mallika Sherawat performed a sizzling number with Zayed Khan.
