Heather Mills goes on the attack again

Heather Mills is on the offensive again after her £24.3 million (NZ$60.8 million) divorce settlement with ex-Beatle Sir Paul McCartney.

She has posted a sign outside her mansion threatening the press with legal action for trespassing, reports say.

The 40-year-old former model placed a sign outside her Peans Wood Mansion in Robertsbridge, East Sussex that read "Private - legal action maybe taken against unauthorised persons found on this property.", Britain's Telegraph reported.

Mills had already called the police about the press, the newspaper reported, but officers declined to act against a reporter who posted a letter through her letterbox on Wednesday.

But Mills relationship with the media has not gone totally sour. She was recruited to be a judge on US billionaire Donald Trump's Miss USA Pageant, the New York Post reported.

Trump said he was not worried about Mills's reputation, saying "So is Omarosa ... and look how well we've done with her".

Omarosa was a participant on Trump's Apprentice television show, and was voted to as the most hated reality TV star of all time in a 2005 TV Guide poll.

In another attempt to rehabilitate her image, Mills has also updated her personal website with messages of support from US Democratic presidential candidate Senator Hillary Clinton and British billionaire Sir Richard Branson.

But the messages are not believed to be current, with Clinton's video clip filmed in 2002, and Branson's almost a decade ago.

In Clinton's clip, she said: "God bless Heather Mills ... for the person she is and the work she does for all of us. I have been inspired by her vital charity work."

Branson's message said: "Initially when you meet her you wonder whether she is to be too good to be true. Years and years later she has been completely consistent. I really do believe she is one hundred per cent genuine and I would kill for her."

Mills also expressed her relief at the conclusion of the divorce settlement in a statement on the site, writing: "I am so happy and relieved that this divorce has finally been settled and I am delighted with the overall outcome as I feel as if a great weight has been lifted.

"I have enormous respect for a judicial system that allows an individual to represent themselves ... no matter how significant the opposition."

Earlier in the week, the judge presiding over Heather Mills's divorce from McCartney described her as being "less than impressive", having a "warped perception" and indulging in "make-belief" in his judgment.
