Mariah Carey’s HIV-positive sister arrested for prostitution (Photos)

Mariah Carey’s estranged and dying sister was arrested after allegedly offering an undercover cop sexual favors Friday.

Alison A Carey, 55, was operating as a prostitute out of a hotel in Saugerties, Ulster County, in Upstate New York when she was caught, cops said.

And according to cops the woman advertised herself online using her millionaire pop star sister’s lyrics, the Daily Freeman reported.

Carey was described by authorities as a ‘transient’ but had reportedly been offering her services out of the hotel – which police are not naming – for a week.

Saugerties police chief Joseph Sinagra said his team had been tipped off by a series of advertisements that Carey had been placing in the ‘adult’ section of an unnamed website.

One of Carey’s advertisements, posted Friday, read: ‘Im a pretty lady looking for guys who are looking to have some fun and get into a world of pleasure that other woman just cant provide two you…’

She promised that she was a ‘woman with the ability to make the earth move for you and to get you to see stars, oh yea with me its, “ITS SUCH A SWEET,SWEET FANTASY BABY, WHEN I CLOSE MY EYES I COME AND TAKE YOU ON AND ON.”‘

The words mirror the lyrics of Carey’s 1995 single ‘Fantasy.’

Two other adverts by the same user were submitted on July 31 and August 15.

Police are now advising those who had sex with Carey to go to their doctors as soon as possible – especially if it was unprotected.

Carey is currently in Ulster County Jail on $1,000 bail. She is due in Saugerties Town Court on Tuesday.

In March, Carey spoke directly to her sister in a video recorded by The Daily Mail, asking the pop star – who is worth an estimated $510million – for financial support.

As well as struggling with HIV, the recovering drug addict was reportedly left with brain and spine injuries after a devastating home invasion attack in April 2015.

In the video, she begged the ‘I’ll be There’ singer, with whom she hadn’t spoken since a huge falling out in 1994: ‘Mariah I love you, and I desperately need your help, please don’t abandon me like this.’

She also said that she had worked as a prostitute in New York City before Mariah Carey became famous, in order to clothe her family.
