Bristol Palin receives death threats ahead of Dancing With The Stars results - Telegraph: "Security was heightened ahead of the final show and producers were considering not allowing them to appear in Times Square in New York afterwards, as is usual at the end of a series.
Ballas was also told to stop contributing to social networking websites as his comments could inflame people.
Programme staff were put on 'high alert' and one said: 'Security is on absolute lockdown. Bristol is surrounded by security guards everywhere she goes.'
Last week a threatening letter with white powder was received at the programme's production offices and the FBI was called in. Tests showed it was talcum powder.
A viewer in Wisconsin recently became so angry after watching Miss Palin perform that he fired a shotgun at his television and became involved in an armed stand-off with police.
Sarah Palin said she had told her daughter that 'the haters are going to hate' but she should 'fly and soar' on the dance floor."
