A beauty queen who claims she was Bill Clinton's mistress has posted a dramatic warning on Facebook that if she dies by 'suicide' no-one should believe it - because Hillary had previously 'beat me down so I'd lose everything'.

Sally Miller, a one-time Miss Arkansas, warned that she believed she could be killed for revealing what she said were threats and intimidation by Clinton allies concerned that their methods would be revealed to voters.

'Please share. Consider this a warning. Trust me, no one is safe,' Miller wrote.

'In this election year, if you read I died….by committing suicide….don’t believe it. Sally Miller.'

Sally Perdue, now known as Sally Miller, was the 1958 Miss Arkansas and in 1994 claimed she had an affair in 1983 with then-Gov. Bill Clinton

Miller posted this message on Facebook, asking readers to 'please share'

Her long Facebook post contains claims that she is being watched and followed by associates of Clinton's campaign.

'She doesn’t care if I discuss my affair with Bill---that’s old news,' Miller wrote. 'She wants to make certain I don’t write about her actions----how she paid professionals to stalk me, frighten and threaten me, and, ultimately, “finish me off.”'

Outside of social media, the Facebook post has been reported by InfoWars.

Miller's allegations of an affair with Bill Clinton in 1983 - when he was governor of Arkansas - was first made in 1994.

She described herself as one of the former president's one-time alleged lovers, joining a list which includes Gennifer Flowers and 1982 Miss American Elizabeth Gracen.

In 2005, she received a $90,000 settlement from a Pennsylvania school that had discharged her after discovering her past claims about Clinton.

Miller used Facebook to detail a series of what she describes as attacks on her by Hillary Clinton, remarking at one point, 'I did a good job of hiding in China for 10 years after Hillary cause [sic] me to lose a job and almost my life.'

According to InfoWars, Miller believes her upcoming book is the source of the attention. She has said she intends to describe her affair with Bill Clinton as well as his alleged drug use during their time together.

Miller is the latest woman to surface from Bill Clinton's past with allegations which may damage his wife's campaign.

Bill Clinton's infidelities are infamous and his relationship with former White House intern Monica Lewinsky even led to his impeachment in 1998.

He also admitted a sexual liaison with Flowers, a former Arkansas state employee, and, as president, he paid $850,000 to settle a long-running sexual harassment lawsuit with Paula Jones.

In addition to Lewinsky, Flowers and Jones, former White House volunteer aide Kathleen Willey claimed that Clinton sexually assaulted her in a private study just off the Oval Office in 1993, during his first term. Willey never filed a legal claim against Bill Clinton over the incident but did write about it in a 2007 book.
