Kerr denies being threatened by stalker

Miranda Kerr has hit back at reports that she and her boyfriend Orlando Bloom were subject to threats by an Australian man.

The Victoria's Secret model, who recently flew back to the US after a quick visit to her home country, had apparently tightened security after being threatened by a Queensland stalker.

Talking about the rumour, Kerr told a Brisbane radio station: "It's definitely not true."

The 26-year-old attended a charity function in Brisbane on Sunday with her mother and was flanked by bodyguards, fuelling the rumours. Kerr told the crowd that she had left Bloom in Dubai despite his initially hoping to join her on the trip.

Kerr was spotted looking gaunt at a Sydney photoshoot last week.
