A new Michael Jackson accuser has come forward to claim she was abused by the singer when she was just 12 years old - and then paid $900,000 to keep quiet.

The woman, who has filed the lawsuit as a 'Jane Doe', has revealed a collection of creepy notes she claims the singer sent her after he 'sexually abused' her.

In the correspondence, written in scrawling, childlike handwriting, Jackson allegedly tells her that he loves her and is 'crazy' about her. Each one is signed off as either Michael or 'MJ.'

A new Michael Jackson sex abuse accuser (pictured with him as a child in the 1980s) has come forward to claim she was abused by the singer when she was just 12 years old - and then paid $900,000 to keep quiet

'Your Valentine's picture was so original and sweet,' one note to the young girl reads. 'I love you sooo much also you're making me love you even more, the more I talk to you. I'm crazy about you. All my love Michael, the Monopoly King.'

In another, Jackson allegedly wrote how much he 'real liked' talking to the girl, adding that she 'cannot play Monopoly'.

'But I love you and miss you every much. All my love, Michael.'

A final pleading note begs the alleged victim to come and visit him.

'Please come and see. Your mother and dad are nice. Bye. I love you soooooo much. M.J'

She has also revealed a number of checks she claims the Billy Jean singer sent her as hush money.

The alleged victim, now in her 40s, claims Jackson began abusing her in 1986 when she and her mother visited his Hayvenhurst mansion as tourists.

She said the Thriller singer had invited them into the house to see his 'candy area', according to TMZ.

Once there he had fondled her genitals, kissed her on the mouth and body and abused her sexually, the lawsuit alleges.

The alleged victim says the abuse continued until she was 15, when she says Jackson began sending her hush money.

The first check began small at just $2,500, but they continued with a $600,000 check coming in 1993. Over three years, from 1993 to 1996, she received more than $900,000 according to the suit which attached copies of the checks and stubs.

Today she is suing for unspecified damages for emotional distress, negligence and more.

Her lawyers say the checks are proof she was paid to keep quiet.

The woman, who is the first female to accuse Jackson of sexual assault, was described as being a tomboy when she met him in 1986.

'She kind of looked like a boy so we don't know if he initially thought she was a boy or not,' her attorney Vince Finaldi with Manly, Stewart & Finaldi told ABC 7 News.

The MJ Estate has not yet commented on the lawsuit.

The woman is one of many alleged victims who claim they were sexually abused by the singer.

The King Of Pop is said to have shelled out nearly $200 million to as many as 20 victims, according to lawyers for two sex abuse accusers. The Jordan Chandler lawsuit alone is alleged to have cost more than $40 million, reports theNew York Post.

Australian choreographer Wade Robson and James Safechuck both claimed they were sexually abused as children by Jackson.

The child molestation claims against Jackson's estate were dismissed by a Los Angeles judge after it was determined he waited too long to file it in court.

But the choreographer has continued his crusade against MJJ Productions and MJJ Ventures, adding new negligence claims in his lawsuit against the companies.

Robson, who first met Jackson when he was five years old, recently filed a new complaint to the companies claiming Jackson operated the most sophisticated child sex abuse operation 'the world has ever known'.

The 33-year-old claims the two companies, which both distribute multimedia entertainment made by Jackson, served 'dual purposes'.

'The thinly-veiled, covert second purposes of these businesses was to operate as a child sex abuse operation,' wrote Robson's lawyer, Vince Finaldi, in the motion.

Robson, who has since worked with Britney Spears and appeared as a judge on So You Think You Can Dance, claims the abuse went on for seven years.

The abuse ranged from French kissing to penetrative sex and only stopped when Robson began 'showing signs of puberty', the complaint claims.

That's when Jackson became 'no longer as interested in him sexually'.

Robson claims Jackson's assistant Norma Staikos was the 'madam' or 'procurer' of the operation.

It was Staikos who Robson's mother contacted when the seven-year-old and his family arrived at Disneyland for a performance with his dance company, according to the complaint.

Robson has claimed that Jackson (pictured together in an early photo) abused him for years after he met the King of Pop and stayed at Neverland Ranch when he was seven years old

Finaldi said Robson wasn't the only child Jackson, Staikos and his companies lured to Neverland Ranch.

'Make no mistake, Neverland Ranch was nothing but a well-orchestrated trap,' he told the New York Daily News.

His new claims argue that the firms 'breached their duty to take reasonable protective measures to protect minor children in their charge'.

Robson at first denied he was abused by Jackson when he was called to testify in the King of Pop's 2005 molestation trial.

Jackson was accused at the time of sexually abusing Gavin Arvizo, a 13-year-old cancer survivor.

During the same trial Blanca Francia, Jackson's former housekeeper, testified that she saw a young Robson and Jackson in the shower together.

'I walked in and they were in the shower,' she told the court, according to a report from the time.

'When I saw it, I saw clothes on the floor by the shower...underwear'

This week, new video was released from the raid of Jackson's Neverland ranch in November 2003, which revealed his memorabilia collection, including a picture of Macaulay Culkin

Francia said she recognized Jackson and Robson's undergarments and that she could hear Jackson laughing in the shower.

Jackson was cleared of all 14 counts of allegations against him in 2005.

Authorities were also reportedly convinced that Michael Jackson had preyed on his own nephews – then silenced them with threats and gifts, sources say.

Two of the singer's nephews and another relative were interviewed by detectives in Santa Barbara County when he was being investigated for child molestation in 2004 and 2005, the New York Post reports.

One of the boys was whisked off to an island by Jackson and bought a brand new car to keep quiet about it, a former detective said.

'We received a credible tip about the nephews and, as with many things that happened during the investigation, Jackson's people got wind of it,' the detective told the Post.

'Jackson spirited the one boy off to an island. Well, when that boy returned, Jackson had also purchased him a brand new car which we understood, along with the trip, was to shut the nephew up.'

Despite this, the 18-year-old nephew had once invited two detectives inside when he was home alone.

The nephew told the detectives that he was not willing to 'talk bad' about his uncle, according to a source linked to the prosecution.

Four years after Jackson's death, Robson sued Jackson's estate in May 2013 and alleged the superstar had molested him for seven years.
