Aussie model Miranda Kerr denies being threatened

Despite being surrounded by tight security, Aussie model Miranda Kerr has denied that she and actor Orlando Bloom are being threatened by an unknown Queensland man.

Kerr, 26, had attended a charity event at Rocklea, in Brisbane's southwest on October 18 with a heavy security contingent to promote the Kids Help Line at an event organised by her mother, Therese.

But she told a radio station that there was no truth to the story.

"It's definitely not true," the Herald Sun quoted her as saying.

It had been reported that an unknown Queensland man had made a threat at both Kerr and Bloom, but a police spokesman would not confirm if a complaint had been made on Kerr's behalf.

At the event Kerr appeared relaxed, as she spent hours at the charity day and took to the stage several times under the close watch of two personal bodyguards and several privately contracted security staff.

Security surrounding the event was tight, with guests required to enter through a manned gate before proceeding through a bag-check area.

A representative for the supermodel would not discuss the matter.
